Photography Through The Microscope!

Beginning with this post I am going to make prints of some of the images on my blog available. More information is posted at the end of this blog. Thanks for your support

Watch face DSC-2184

In the book Zen and the art of motorcycle maintenance the author (Robert M. Pirsig) quotes an instruction booklet, that said “assembly of Japanese bicycle require great peace of mind.” Macro and micro photography require that your peace of mind increase in direct proportion to the reduction in the size of the object you are photographing. It gets more difficult, and it requires more patience, as you get closer.

Most people approach macro photography by purchasing some sort of macro lens which enables them to reproduce picture of an object at perhaps one quarter the size of the object in real life on the sensor of their camera, maybe even bigger.  So, one quarter reproduction means that if you had a 25 cent piece, a quarter in US language, you could take a picture four of them and stacked across the short distance of a full frame sensor sensor. And they would fit. The quarter is an inch wide and a full frame sensor is an inch wide (and an inch and a half long). If the quarter filled a full frame sensor it would be a 1:1 capture, or life size.

Macro photography is occasionally discussed in terms of where it begins and where it’s simply a close-up. I’m not sure that that’s terribly useful, but, when you are less than three feet from your subject with a more or less normal lens, you’re pretty close and it isn’t necessarily difficult to make that picture, depending upon the equipment you’re using. As you get within less than an inch of your subject it gets to be extremely difficult to shoot, and when you are within one or two millimeters of your subject, it becomes almost impossibly difficult to photograph. What I’m going to explain here is photography with the microscope, which is generally photography within less than an inch of the subject.

I will discuss other ways of doing close-up work in other postings. This posting is concerned with very, very close microscope work. This is not the usual way I approach this subject: in the past I’ve discussed macro photography and built up to micro and microscopic photography. That might make more sense. However, I’ve recently posted a lot of photographs made with the microscope, and so I hope that many people might be interested if I start there.

Leitz Microscope

The first thing about the microscope is to understand that the actual equipment that you need to do this kind of photography is easier to get, and less expensive, than you might think it would be. That’s important because one of the things I would hope that this discussion does is to encourage you to try this kind of micro photography or microscopy if you want to be more formal.

Leitz Microscope set-up

Before I write about the individual components of the camera/microscope combination, I’d like to give an overview of the set-up, from top to bottom. At the top is a digital SLR, the currently available cameras would be good for this. Next is a T-mount (more below) which connects the camera lens mount to a microscope adapter. This adapter is basically a hollow tube that fits between the camera and the eyepiece tube. The eyepiece is in the eyepiece tube, and it’s the first part for the optical system. The eyepiece tube is connected to the microscope head, where the lens or lenses are mounted. That lens is called the objective lens and it is the second part of the optical system. Below the objective lens is the stage, which is where you’ll place your subject. Under the stage there will often be an iris/condenser device, which can be used to change the quality of the light coming through the subject. Probably most scopes have a mirror below the condenser, but a few will have a light source. I think a mirror is more useful. At the bottom is the base, which is usually heavy to keep the whole thing stable.C14 The condenser, it helps to focus the light onto the subject

The large wheel is course focus and the small one is fine focus. They are often set up this way on modern scopes

The condenser, it helps to focus the light onto the subject.

A decent student grade microscope can be had for around a hundred and fifty dollars. This will do the job. Of course, you can spend much more on a microscope, but since you are not trying to accurately reproduce pictures of cell division or tiny crystalline structures (at least I’m hoping you’re not) a student grade microscope is a good choice. A student grade scope has course focusing and fine focusing, two separate knobs. It takes standard interchangeable eyepieces and interchangeable objective lenses with a standard thread. I’ll put a link to a student scope, and the rest of the stuff, at the end of the post.

Objective lenses on Lens turret

Eyepiece

In order to understand the reproduction ratio of a microscope for viewing it’s pretty simple. The eyepiece and the objective lens have numbers for their power, say 10x or 4x. Multiply the two numbers and you have the power of the system. So, if you have a 4X objective and 10X eyepiece, you would be viewing at 40 times life size, which is a nice range to work in. I’m not actually sure that this is exactly the power on your camera sensor, but whatever it is you’re damn close. When you make a print of the capture or reproduce it on your computer screen it gets larger still. So, you are frequently looking at things that may be a hundred, two hundred maybe even three hundred times life size on your computer screen, which is pretty impressive.

Microscope Adapter and T-mount

The adapters that you need to do this, in addition to the scope, are first a microscope adapter. This fits around the eyepiece tube on a standard microscope. Is available for less than $40. Surplus shed would be a good place to start looking for them. In addition, you will need a T-mount adapter. T-mount was an early interchangeable lens mount that is still used today. A T-mount lens could fit onto cameras with several different lens mounts, if you used the right adapter. And it remained unchanged and in use pretty much to this day. There are mounts for most current cameras, even mirrorless. T-mount is also used for telescopes and some other optical systems. You can also get old mirror lenses that use t-mount adapters. They can be a lot of fun. T-mounts are available from Surplus Shed and B&H Photo and any of a variety of suppliers.

The camera on top of the scope

Microscope and T-mount attached. They are screwed together

The microscope adapter is two pieces. It’s easier to mount the small piece on the scope and mount the larger piece onto the camera and then put them together on top of the scope.

You should start with the microscope arranged vertically. Most of the student grade microscopes, in fact, I think all of them, will tilt backwards to make it easier to sit and view your subject. Unfortunately, if you mount your camera on the microscope in this way, it will probably fall off the microscope and that would be a bad thing. So, you’ll set up the microscope vertically. Important safety tip. It is also very important to set the camera to use the self-timer. If you trigger the camera directly with the shutter release you will shake the camera and get fuzzy pictures. You could also use a remote release, but the self-timer works very well for microscope work.

Microscope lenses- Shown are a 4X Plan, a 25mm Zeiss Luminar and a Spencer 10X. This is the group I’ll usually put onto the scope.

I would always start with a 4X objective lens. I say this because one of the problems that you’ll get into, as I mentioned earlier, is the closer you get to your subject the more difficult it is to manage taking a picture of the subject. With a 4X objective lens, the lens will end up being between a quarter and three-quarters of an inch from your subject. That gives you just enough room to light the subject from above. It also gives you room to put a filter on the lens; it gives you room to do a whole lot of things. A 10X lens will be less than 3 millimeters from your subject, which makes it impossible, or close to impossible, to light your subject from above. You’ll only be able to work with transparent subjects with the 10X or more powerful lens. It’s more difficult to manage the focusing or positioning with the 10X lens. When a professional microscopist uses a 100X lens she/he will usually add oil to the top of the subject and then put the lens into the oil. There’s less reflectivity if you do this. You would only be able to photograph transparent subjects with light transmitted from below the stage. I have not tried to do this, and, unless I find some transparent subject that seems absolutely compelling to me, I am unlikely to try it in the future.

Eyepieces, Shown are a Leitz 6x and 10X and a Wollensak 15X and 20X

One of the things that may not come with a student-grade microscope is multiple eyepieces. And this is one of the things that you might very much want for photo microscopy such as I do. Since it’s so difficult to use more powerful objective lenses, you may find yourself wanting to change the eyepiece to change the power of the scope. Eye pieces come in a variety of strengths. I own a 4X eyepiece, a 10x eyepiece, a 15x eyepiece and a 20x eyepiece, which gives me some variety of reproduction powers. Surplus shed carries a number of different eyepieces and they would be a good place to start looking for eyepieces. A student grade microscope usually comes with a 10X eyepiece and that is a good place to start. Neither standard eyepieces or objective lenses are terribly expensive, compared to camera lenses. There are some special purpose objective lenses if you’d like an upgrade. If you find a PLAN objective lens it will be sharper than the lenses that come with most scopes. The biggest difference might be that an inexpensive objective lens will be more likely to be fuzzy at the sides of your image.

Geared stage

Most student microscopes have clips which will hold down a regular microscope slide. Then you position the slide, or other subject by moving it with your fingers under the scope. This is the biggest problem with inexpensive microscopes. Better scopes have a geared stage to move the subject around under the scope. If you really enjoy photo microscopy you might want to get a scope which has gears to control the position of the subject.

Lowell Pro light with Barn Doors

The next thing you will need is a light source. Most student-grade microscopes and in fact most fancy microscopes only have a mirror below the lens. Most scopes also have a condenser between the mirror and the stage which changes the spread of the light that you’re using. I find that the condenser is not terribly useful to the way I approach microscopy, but you may find it helpful. Some student grade microscopes will not have a condenser. The actual light source that you use can be something as simple as a desk lamp or even the room light. And that will work very acceptably for an awful lot of work that you might do with the microscope. Look for a lamp that has a continuous spectrum or perhaps an LED light source. Stay away from fluorescent light sources because the spectrum can make it very difficult to get a true color reproduction or can change the color reproductions in unexpected ways. I find that I rarely look for accurate color in micro photography, especially because the images aren’t things we can usually see with the unaided eye. Often, I will use the 3200º Kelvin quartz light and either not compensate for the warm color shift of compensate in Adobe RAW when I open the image. A small light source gives you more control than a broad light source. At this point I am using a Lowel PRO quartz light, which provides much more light than any desk lamp. I like this a lot, but it’s not available new, there are generally several of them on eBay pretty inexpensively. Lowel still makes several more powerful quartz lights, like the Lowel Omni or Tota quartz light but these might be too hot for microscope work (they do get extremely hot).  A bright light source is especially important when I start to filter or modify the light because I will still have enough light to actually see the subject. Even without a filter it’s dark through a microscope; more so when the light has to go through the camera and into the viewfinder, after it leaves the microscope eyepiece. The next problem is to position the light source. The Lowel PRO quartz light can be attached to a regular light stand mount or it can be attached to a tripod mount. This enables you to use a ball head or another tripod head to position your lamp in relationship to your subject. This light also has barn doors which give you more control over the light. You can also move the microscope mirror which will help position the light; that is if you are lighting your subject from bellow. If you’re using a 4x objective lens you can also light a subject from above, which makes positioning the Lowel PRO light with a tripod head even more helpful. You can also use a strobe to light, even a dedicated camera flash. This can increase sharpness, because camera shake can be a problem, BUT, it’s very difficult to be sure what your subject will look like when you take the picture. Also, you’ll still need a bright light to focus.

The 4X lens focused on a feather. You have a good amount of room between the lens and the subject.

If you are using the 4X objective lens you will find that most of the focusing can be achieved with the course focus wheel on your scope. The fine focus wheel is useful when you try to use that 10X lens. You will also find that the objective lens will stay at about the same distance from you subjects, so if you get a sense of that distance you can set the scope at about the right distance before you look through the camera. Your actual focus is achieved by looking through the camera viewfinder. Since your microscope is set up vertically, it may help to place the scope on a low table or get something to help you stand above the scope. As you might imagine depth of field, holding things at different distances form the lens in acceptable focus, doesn’t really exist with microscopes. With few exceptions, notably Zeiss Luminar lenses, microscope lenses do not have diaphragms, so there is no way to adjust depth of field, that is if you had any… What you can do is use Photoshop to do focus stacking. In order to do this, you need to take a several pictures at different focus points. Photoshop will enable you to combine these images into a single image with better focus. This can be a very helpful technique. While it is outside the scope of this particular post you will find that there are plenty of tutorials on line. Or, you could wait for me to do a post about modifying micro images in Photoshop. If you do take images for photo stacking, you’ll want to take them at the same exposure.

Image without focus stacking

Image with focus stacking DSC2130

When I first worked with high magnification optical systems exposure was very difficult to calculate. I had to compensate for long bellows extension on the view camera as well as reciprocity failure form the long exposure times. It is still astonishing to me how much easier it is to get a great exposure with a digital camera. If you set your camera on aperture preferred, you’ll get a good exposure. You may want to add exposure compensation correction, if you want a darker or lighter exposure. You might want to see what an image looks like at different settings, just to get a better feel for how you can interpret your subject. Of course, you can also do a lot of interpretation after you capture the image in photoshop. These changes in exposure calculation are perhaps the biggest improvement in micro photography that I’ve seen in 40 years. The massive improvement in the amount of information that a sensor records, compared to 35mm film, is also very significant. I used to do micro photography with large format cameras and transparency film, which was really quite difficult.

Sodium Thiosulfate

As you look at the pictures of the set-up and the various tools I use, you might want to begin thinking about subjects. I’ve recently done some nice work with old watches and some shiny goo meant for hair. Jerome Russel used to be a client and they made some very shiny hair care products with glitter and other reflective materials. I’ve included shots of both here.

Of course, a lot of things have interesting colors. Below are a couple of shots of dried Selenium toner, which is used in the wet darkroom to add color to B&W prints.

Let’s not forget living things. These are a couple of pictures of butterfly wings. Bet you didn’t visualize them looking like this.

I mentioned filters above. There’s a lot of science behind this trick, but I’m going to cut direct to the chase. Put certain transparent materials, things like plastics and sodium thiosulfate (B&W fixer from the wet darkroom) between two polarizing filters. As you rotate one of the filters colors will start to appear. FUN! But, as I mentioned above, you need a lot of light. These shots are of a plastic prop ice cube. You can get interesting results, but you’ll need to experiment. Frankly all of photo microscopy requires an experimental attitude.

As I mentioned at the top of this post, I am now offering prints of many of these images. If the caption has an index code like DSC1234 you can buy a print! Right now, all prints are set to fit on an 11×14 inch piece of paper. If the image is too thin it will have white paper on the sides. I am printing with an archival ink/paper combination. Prints are shipped by USPS priority mail to anywhere in the US that’s covered by Priority Mail service. The price is $75 for the first print and $60 for each additional print ordered at the same time. Please e-mail me at john@siskinphoto.com and include index code and your address. I will send you a PayPal request to arrange payment. I will be adding old and new images to this service. If you see an image on my site you would like to purchase please tell me where you found it and I’ll try to make it available to you. Thanks for your support!

Courting Chaos

Curt #5
Published in Black and White Magazine

This post is about my Courting Chaos images, a group of images I made over more than two years, while I was working and teaching in Indianapolis. Black & White Magazine is going to publish one of these images in a few weeks! The work evolved over more than a dozen shoots with an 11×14 camera. The first show of this work was on November 2nd 2018 at Indiana Landmarks (1201 Central Ave, Indianapolis, IN 46202). Before I get any further, I should thank David Kidwell for assisting all through this project and Julie Powers for make-up and models. This work wouldn’t have happened without them.

Andrea #5

These images are figure studies handled with a very unusual and chaotic photographic process described below. Many of them are nudes and several of them are disturbing. I’m writing about the process in this post and also some thoughts about the results. I’ve enjoyed the entire project as a voyage of constant discovery. I really had no idea how the project would evolve when it began. My response to the images continues to change. I hope the images invite the viewer to create a narrative from them. My narrative involves ideas about escape. I hope you’ll find them interesting. My perception of the project continues to evolve.

Cassie #14

There are a lot of places I could begin to explain this work, because this project integrates traditional photographic techniques that I learned in high school with digital image manipulation techniques I’ve learned as recently as a few months ago. The project integrates inspiration from my first trip to Europe in 1971 and my visual inspiration continues to evolve to today. The greatest challenge, for me, is coming to accept chaos to be a co-creator in my photography. As a commercial photographer, for more than four decades, I’ve been fighting chaos. A commercial photographer generally wants to control and direct images to produce effective visual communication. In this project I’ve used special processes to push the images into shapes I couldn’t predict or control. The results have been the most surprising images of my career.

Gordon #1

I saw a series of sculptures by Michelangelo called the Prisoners when I was in Europe in 1971. I was about fifteen at the time. At first these images appear unfinished, especially in comparison with the David sculpture which was in the same museum. When I continued to stare at the pieces they seemed to be struggling to escape from the marble. The effect was quite surprising to me at the time: the seemingly unfinished sculpture conveyed movement while David sculpture remained a single moment of time. It’s now almost fifty years later and I still remember the effect and the details of these sculptures.

Bree #11

I remember seeing an Edward Weston photograph of a pepper just a few years after I saw the Prisoners. This image also had a lasting effect on my development as a visual artist. The design of the image was beautiful, but the medium: a silver gelatin photograph was also gorgeous. Of course, I had seen photographs before, but this was a contact print from a large format negative. Weston’s excellent craft created particularly beautiful prints. Over the years, in my classes and in working with photography, I’ve often met people that assume photographs are somehow independent of the medium in which they’re presented. For example, a person might think that they’ve seen “Moonrise Over Hernandez” by Ansel Adams because they’ve seen it on-line or in a magazine or a book, but a fine photographic print, made by Ansel himself, has a different effect than an image from an offset press or a computer display. In order to appreciate any creative work, it helps to see the work as the artist intended. Of course, there are many posters of paintings by Van Gogh or Monet and so many others, but is seeing these posters equivalent to seeing the original painting? It was the effect of the actual Weston print that allowed me to see beauty of the medium. I hope to share the actual prints of Courting Chaos again soon.

Of course, there are so many images that affected my way of seeing, and these images in particular, but the work of Man Ray is most important for this project. Man Ray worked in a variety of media: doing sculpture, painting and photography. My perception of his work changed when I saw original pieces at the Getty in Los Angeles. One aspect of his images was important to this project: he was solarizing his negatives in a way I had never seen before. The way that Man Ray integrated innovative technique with creative images is spell binding.

Pernicamera

On another level this project began when I purchased an 11X14 inch camera. While it’s not necessarily difficult to think about scaling up a camera “it’s just the same thing only bigger” the reality is pretty impressive. A full frame dSLR uses a sensor that is 1X1.5 inches, regardless of how high the sensor resolution; it’s a small area. The camera for this project has a capture area of 11X14 inches. In addition, while the sensor may have high resolution, film resolution is on the molecular level. The total amount of information you can capture is mind blowing. The costs of the thing are pretty impressive as well; a single sheet of 11X14 inch film costs eight dollars. Adams used 4X5 inch camera much of the time; Edward Weston used an 8X10; Brett Weston did use an 11X14 camera occasionally. The problems of using a camera this size are not just expense and weight, it also needs a lot of light. So, when I got the camera, I wasn’t sure that I would use it much, maybe just a couple of times to prove I could master the thing. Then, after a lot of thinking, I came up with a way of using the camera to make images that I couldn’t create with any other camera. I decided to explore solarizing (re-exposing) the negatives.

Bonnie Hunt, Hand
Print Solarization

This is similar to what Man Ray did, during the processing of his film he re-exposed the negative to light. This creates a reversal effect. This was a pretty common process when I was in high school, but we solarized prints rather than negatives. When you solarize a print the white area of the print black or gray, which can look pretty compelling. It’s impossible to entirely predict what will happen, and even if you do the same thing twice, the results will be different. The thing about Man Ray’s solarization process is that he turned the black areas of the image white AND he could make multiple prints that were the same. This was because he solarized the negative rather than the print. This creates another big problem: you have to process modern film in total darkness (yes, even black and white film) so you can’t see what you’re doing. When Man Ray did this people used orthochromatic films; films that couldn’t record red light, so he could see what he was doing. I realized that I could shoot 11×14 photographic paper, which can be used under safelight. Since I have an 11×14-inch scanner I could take these negatives, which were on paper, and scan them. This enables me to interpret the images in Adobe Photoshop. The large area of the negative is an advantage with this process because you can choose to re-expose and re-develop specific parts of the image. As I mentioned, what actually happens to the image when you re-expose and re-develop is chaotic, almost totally unpredictable. Thus, I am courting chaos in making these images.

Mindy K #7
Original Negative Scan

A great advantage of shooting the photographic paper, rather than film, is that the processing is quick and easy. You can develop the RC paper in about a minute. Even with re-exposure it was only about 5 minutes from exposing with the camera to seeing the negative in white light. Almost as quick as Polaroid! In addition, since the large scanner was in the studio I could scan and reverse the images in short order, so the subject was able to leave with digital prints! This project benefited immensely from the immediacy of this medium. For many of the models, this was their first experience in seeing photos develop.

Cassie #1

This project is also the result of the work of David Kidwell, assistant extraordinaire, and Julie Powers, makeup artist for angels and devils. Julie did a couple of really remarkable things for this project: first she designed the make-up for all the models. This is tougher than it might appear because the Multigrade paper doesn’t react to color in an even way: reds and yellows are very dark while blues are brighter that you would suppose. Julie also arranged for all the models, THANKS! David managed set up and kept me on my feet all through the shoots. Now that I’m in my sixties I couldn’t have done it without him! Each of the models was special. It can be difficult to come to terms with normal pictures of yourself, it’s more of a challenge when you’re teaming up when chaos. You know that all of the images will present you in unpredictable ways. My thanks and gratitude to all!

Rachel #10

In another way this project began at University High School in Los Angeles, specifically in bungalow L79. At sort of the end of the campus was the photography classroom. I first learned about photography in that classroom. The instructor was Arnold Rubinoff. Arnold was teaching things that really weren’t common in high school photography, back then. I remember learning to make color prints from him. One of the things we learned was how to do solarization. He also introduced us to Cyanotype prints. Half of the show was printed as cyanotype images. You can see those prints at this link: https://siskinphoto.com/blog/?p=3630.

Framed cyanotype print for the show

There are a number of important technical insights that led to this project. One of the first problems that had to be solved was the cost of film; if film is too expensive it keeps the photographer from taking risks. One other advantage of the paper is that it has good light sensitivity: Ilford Multigrade is about ISO 100. Another important moment was when I realized that I had an oversized scanner. My original thought was to remove the emulsion from the paper and put it onto a clear base, which would have been very difficult. Scanning the images was easy and quick. I was then able to make new negatives on clear film using a digital printer. These prints, both silver and cyanotype, are much more beautiful than the digital prints. For this show I used multiple coats of cyanotype chemistry on blotter paper. The images have a very dark maximum tone as a result. Because the prints are hand coated each cyanotype print is different, even if made form the same negative. Cyanotype prints do change over time, which is part of the charm. For the silver gelatin prints (check here to see: https://siskinphoto.com/blog/?p=3571) I used Ilford Multigrade Warm Tone Fiber base paper. Fiber base papers use a barium clay coating called baryta that produces the white tones. In addition, when you air dry a glossy fiber-based paper the surface looks fabulous. I also toned all the silver gelatin prints with selenium, which makes a more agreeable print color as well as adding to the stability of the final print.

Actually shooting with the camera is pretty tricky. Some things are like working with any large format camera, for instance the image is upside down and backwards on the ground glass. Over the years I’ve become used to that. One problem that particularly affects the 11X14 is bellows extension. The closer your lens is to the subject the further it is from the film. I know this seems exactly backwards, but trust me it’s the way it works. What might not be obvious is that as the lens gets further from the film, there is less light on the film. If you are shooting a head and shoulders portrait with a 35mm camera you don’t have any bellows extension; if you’re shooting with 4X5 film you might lose half stop to bellows extension; with the 11X14 camera you’ve lost about 2 stops of light to bellows extension. This means it’s dark on the ground glass when you’re focusing and composing AND you need a lot of light to make the exposure. Most of the time I was using between 5000 and 7000 watt-seconds of strobe power to make the exposure. My lens was generally set between f11 and f16. While this seems like it would give you plenty of depth of field on a digital camera, on the 11X14 it gives you only a matter of millimeters of focus depth. So, focus is critical, which makes it very important for the model to stay in place! Another aspect of bellows extension is the way it affects your lens choice. The normal lens, if there is one, for an 11X14 camera is about 450mm, or 18 inches. If you were shooting like you do with a full frame digital camera, you’d need about 1000mm (39 inches) of bellows to bring the lens into focus. That makes the camera really difficult to keep stable and to adjust. The answer is to shoot with shorter lenses, which bring the camera closer to the subject. My favorite lenses for this project were a 12 inch red dot Artar from Goerz (f9) and a 14 inch gold dot Dagor (f8) made by Kern for Schneider. I use the 12 inch Artar for head and shoulders and the 14 inch Dagor for full body shots. I used a few other lenses on occasion including a 48cm Goerz Dogmar (f5.5) and a 270mm Wide Angle G-Claron from Schneider (f6.3), but they just didn’t keep the subject/camera distance in a good range.

The camera itself has some basic challenges. The fact that it’s a working 11X14 camera must be in its favor but it’s built out of parts from other cameras. It’s built on top of a drawer, like something out of a card catalog. This allows it considerable expansion, but it also means the camera isn’t portable. It weighs a lot, so the tripod needs to be a beast. The focus skips out of alignment, which is annoying. The bellows sag. There is a plaque on the camera proclaiming it as the Pernicamera Model Number 0001, built in 1995 to 1997. I’d like to meet the person who built it. I don’t use a shutter with the camera at all. I keep the lens open, but all the illumination, once the paper is loaded, is from safelights. I trigger the strobes with a radio slave to make the exposure. This makes it easier to do multiple exposures and to move the subject between the exposures.

Digital Shooting is Different!

Filed under: Basic Photo Technique,Digital Photography,Looking at Photographs — John Siskin @ 3:12 pm

There are over 600 images attached to this blog post, probably excessive… Please take a look. Due to the number of images I’ve decided to place them after the text. If you only want to look at the images please scroll right through the text. Please note, all of these images were shot by me in 2020. They are covered by any and all applicable copyright law. Thanks!

I’ve had several discussions, over the years about the difference between digital and analog photography. When I first started to do a blog I did some posts about the things that hadn’t changed, the things that carried over from film to digital. Some of that stuff is in this article: file:///Users/siskin/Downloads/basic-1.pdf. This made the point that many of the basics of photographic capture, things like aperture and shutter speed and design, don’t really change when you’re shooting digital. Over the years, I’ve met a lot of people, including photo instructors, who want to work with a digital camera as if it is a film camera. You can certainly do this, but it ignores some of the great advantages of digital shooting.

Since I got out to New Mexico most of my time, photographically, has been spent with film cameras. I don’t want to try to justify that choice, except by saying I’m having a lot of fun playing with film cameras. Since most of my time as a commercial photographer and teacher, for many years, has been largely spent with digital cameras, I’m very aware of differences in the way I shoot digital and film. This blog post is about a very basic and EXTREMELY IMPORTANT, differences between shooting film and digital: MONEY and TIME. Every time you press the shutter button on a film camera you have committed to a financial expenditure. Maybe you think, but it’s not a lot, it shouldn’t be important to your shooting decisions. Here’s the thing, it’s not a lot, if you shoot a digital camera like a film camera, BUT, if you shoot it like a digital camera, it should be a lot. Later in this blog I’m going to present the shots I took at Leonora Curtin Wetlands, a couple of weeks ago. The first time I went with a film camera, and shot about 8 images. I went back a few days later with my digital camera and shot 700 images. The film cost about $8 dollars. I took be about an hour to process the roll and another hour to scan the images. If I’d shot film, I’d have spent about $85 dollars and say a couple of days to process and scan all those shots…

My Mamiya Press camera is a little tricky to use and it has questionable ergonomics; the Nikon D800 is easy to use and a dream to handle. Why do I insist on working with film cameras, and while we’re at it why do people climb mountains… Ansel Adams often spent a lot of time on making each image, at best his 4×5 camera and tripod took minutes to set up, so he put a lot of effort into each negative. Jay Maisel was also, originally, a film photographer. Instead of a 4×5 camera he was using 35mm cameras. The thing about Jay is that he shot a ton of film! I’ve heard him speak and have some of his books. One of my articles even appeared in a magazine that featured his work. He is a terrific photographer and you should look at his work. Every story I’ve heard about him stresses how many photographs he takes, how much film he used. It was EXPENSIVE to shoot like Jay. Of course, he had a big budget for his shoots…

The thing is that digital capture separates pushing the shutter button from emptying your wallet. SO, SHOOT LIKE JAY MAISEL!!

But then I have to edit all those images…

Of course, did you think that buying an expensive camera made you a better photographer? Editing makes you a better photographer.

Over the years I’ve talked to a lot of stock photographers, magazine photographers and photo teachers. The stock photographers and the magazine photographers will always tell you to “frame loosely”, leave a little extra space in your composition. And, they’ll remind you to shoot both vertical and horizontal versions of your subject. The reason is that when you sell that image you don’t know what the buyer will want to do with it: maybe they’ll need a little extra room for a title or for a label. I’ve heard a lot of photo teachers harangue students to make their compositions in the camera; to do their final framing in the view finder. This is a good exercise, and it was sort of important if you were shooting slides for projection, but it’s not good advice for digital shooting. Those ideas were important when folks were shooting 35mm film. Today, people have forgotten how little resolution 35mm film had. You could make a good 8×10 inch print, if you didn’t crop much. If you had a really graphic composition a bigger print would work, but a double page spread in Life Magazine wasn’t going to look great. So, people were using bigger film, much of the time. Like my Mamiya Press camera, which uses 6x9cm film. As you may know, I often shoot much bigger film, 8×10 inch and 11×14 inch negatives! Modern digital cameras have huge files, which can translate into either huge prints, or cropping without a loss in image resolution. The files from my Nikon will print at 24×16 inches at 300 dpi, fantastic resolution! Even the files from my phone camera have more resolution than the 35mm film I used when I started out. So shoot loosely!

In the old days, most of us spent a good deal of time in the darkroom. It was part of basic training. First, if a photographer didn’t understand the whole process, he/she was often handicapped in dealing with a professional lab: you didn’t know what they could and couldn’t do. Of course, there were lazy photographers, people who dropped the film off and assumed that the lab would do right by them. If you were a wedding shooter, and went to a pro lab that was good at weddings, this generally worked out. If you dropped your film off at the drug store your work often looked lousy. Today, with digital, a good photographer needs to have a real familiarity with digital image processing. You can get services like www.deepetch to do the work for you, but just like with an old school professional lab, you need to communicate with them. You can also work with Photoshop or Lightroom and get great results on your own, and your hands won’t smell like fixer. The bottom line is that you’re going to have to have some involvement in the interpretation of the image after the shot. Shooting loosely doesn’t mean that your finished images should be loose!

I’ve already done a blog post about editing: https://siskinphoto.com/blog/?p=3362. Editing is very difficult process; it can be heart breaking. In this post I’ve included a proof sheet of the 8 images I shot with my film camera at Leonora Curtin Wetlands. One shot was ruined by my mistake, and I took 3 shots through Photoshop. This was a quick shoot; I was only there for about a half hour because the place was closing. Because of the short time I kept the wide-angle lens on the camera the whole time. Three out of eight is pretty good odds…

I went back a couple of days later with the digital camera: Nikon D800. I had a few hours to shoot, which would have changed the original shoot as well. The big change was that I shot like a digital photographer. I shot 700 images. I’ve attached 608 of the images to this blog. I kept the others back because they had people in them and I didn’t bother to get model releases from those folks. If you plan on selling your shots you better plan on getting model release forms filled out. Regardless, it’s a hell of a lot of pictures. I edited these files several times. It took a while, and I put it off for a while. It’s often better to edit after you’ve spent a few days away from the shoot. You’re more likely to edit the images for effect, rather than the experience of making the shot. I used to ask students to trade raw images with each other so that they could get the feeling of editing, truly independent of shooting. This is great exercise. We often forget that the viewer won’t have the experience of making the shot, they only have what we choose to share. I finished 15 shots in Photoshop, not such good odds, but odds on, better images. I’ve included all these images so that you can get the idea of what it’s like to edit a big shoot.

For the digital shoot I had four lenses, all manual focus. It’s not that I don’t have, or use, autofocus lenses, but I felt I needed some practice with these lenses. As I’ve written before, it’s extremely important for photographers to PRACTICE. I had the Vivitar Series 1, 90-180 Flat Field zoom lens F4.5. This is a very unusual lens design. It was supposed to have been designed for medical photography. The one I have now is wicked sharp, but what really makes this lens different is that it CONTINUOUSLY focuses from infinity to macro. I know of only one other zoom lens that would do that: the Nikkor 70-180, discontinued now. Both these lenses are rare and rather expensive for older manual focus used lenses. The Vivitar is really great for shooting product because it has a tripod collar, which makes it really easy to charge the camera orientation without changing the centering. I also took the Lomography Daguerreotype Achromat. This is a modern lens built with a similar optical design to 19th century lenses. It’s a beautiful thing, actually gold plated. It makes very soft images. You’ll be able to pick them out of the attached images pretty easily. I was using it wide open, f2.9, which adds to the softness. Then I took the Nikkor 35mm PC. lens f2.8. This is a very manual lens with a manual diaphragm. What makes it interesting is that it is a shift lens. You can move the center of the lens in relation to the center of the film. Usually this is used for shooting architecture, but in this case, I just wanted to play with it. Finally I had the 14mm f2.8 Rokinon, which is just incredibly wide! There are no prizes for figuring out which images are made with which lens. In fact, since these lenses don’t leave a trace in the exif files, I don’t know myself. I really should keep better records.

I am sure you would choose different images to work with than I did. I am sure you would process the images differently than I did. That is an essential part of our individual expression. I would like to hear your thoughts about these images. Please e-mail me at john@siskinphoto.com with your thoughts!

Copying Artwork and Photographs

I wrote this a few years ago when I was teaching at BetterPhoto. Recently a friend asked about copy work, so I thought I’d re-post it here. The basic ideas are still valid, but today I would use different strobes to do the work. I hope you find it interesting…

Wow, look at how old that computer is… The cover for the Style Guide for Bagadasarian Productions.

When I started my photography business a few decades ago my commercial client was Bagdasarian Productions. They made the Chipmunk animated cartoons, with Alvin, Theodore and Simon. They were working on a full-length movie about the adventures of the Chipmunks. One of the keys to animation, back in the eighties was high quality painting for backgrounds. Those paintings were done here in Los Angeles and then shipped to Korea for the character animation. My job was to make high quality copies of the backgrounds so that the background painters would be able to refer to them in order to maintain accurate color and style. Since then I have done copy work for businesses, artists and galleries. Copy work is pretty simple but it must be done very carefully in order to get the best results. I often do copy work in the living room, since I keep my finished work at home.

The basic layout of a copy job is to have the camera back, whether film or sensor, parallel to the original. The lights need to be between 30º and 45º from the plane of the original. In this range they light the original but you don’t see reflections of your lights in the original. You can even shoot through glass! The lights need to be far enough from the original to even out the lighting. In the example with this article the lights are about five feet from the center of the original. You need the lights further away from a larger original. The reason for this is that if the distances from the light to the corner of the original and to the center of the original are significantly different you will not be able to even out the light. The amount of light that makes it to the subject goes down as the distance from the light source increases. So, if the distances to different parts of the original are very different you will not be able to even out the light. In the example the difference between the light on the center of the shot and the corner is 1/10th of a stop, pretty small.

This is the one area of digital photography where I still use a light meter. When I set-up a copy job I put the lights an equal distance from the center of the original. I also point the lights at the original. Then I use the light meter to move the lights into the most advantageous position.

As I mentioned above, in this case I was able to get the lights to almost perfectly even. It is very difficult for the eye to see differences of less than 1/3rd stop, so if you can get your lighting even to the 1/3rd stop level your light will be even on the copy. I also use diffusion domes over my lights to make them more even.

You might need these if your lights are close to the original, as you move the lights further back, they don’t matter as much. I generally use them, but then I already have them. I will usually use the lights directly, to reduce the chance of reflection. If I am photographing a piece of art with an irregular surface I will probably use umbrellas to reduce the shadows on the irregular artwork. If I am including the frame in the copy I will also use the umbrellas to reduce the harsh light on the frame.

The kinds of lights for copies are also important. The easiest lights to use are strobes. Strobes have a color balance that is the same as daylight; this is a big advantage if you are using film to make copy slides. You can use strobes in a room that has existing light; the room light will be so much less than the light from the strobes (if you have reasonably powerful strobes) that the room light won’t affect your shot. If you can remove existing light from your location (including daylight) you can shoot with quartz lights. These lights are designed for photography and they have the qualities to make good copies. I would avoid the tungsten photo bulbs that look like regular light bulbs; they change color too quickly. I would not use any fluorescent lights for copy work, although digital cameras can balance for them reasonably well, they do not have a continuous spectrum. Consequently you will probably have problems achieving accurate color everywhere in your image.

Whatever light source you decide to use you will need to do a color balance if you are using a digital camera and a color test if you are shooting transparency film. The key to doing a good balance with a digital camera is to use an accurate grey sample. I use a GretagMacbeth ColorChecker, to keep things accurate.

I use the grey samples on this card to set my balance on the digital camera and the whole card to test my film. Getting the color set accurately is a very important part of copying, so it will be important to check the best way to do this on your digital camera.

There are popular copy stands for doing small copies, say 11X14 inches at the largest. These are faster than using than my tripod set-up. If you are copying a large amount of originals from 4X6 inch to 11X14 inch you should check these out. However, if you are doing larger originals or doing copy work less often you should consider a Side Arm attachment for your tripod. I use a Bogen/Manfotto 3059 with my Gitzo tripod; you can mix and match in this area. The side arm mounts on the tripod legs and then the tripod head mounts on the side arm. I cover the side arm with black Duvateen fabric when I am shooting products under glass or very glossy originals.

There can be enough light spilling onto the side arm for it to reflect in the picture. The key to keeping your copy square is to be able to get the original parallel to the camera back. Before you do the leveling get the camera into about the right position, because if you have to move the camera you may have to level it again. I use two surface levels to make the camera parallel to the original. I place one on the original and one on the camera back. This is generally a part of the procedure that requires some patience. The object is to get the two bubbles in precisely the same place.

I have used several different types of levels over the years, these little round levels work pretty well. The key is to not be in a hurry, and to double check if you move the camera. Remember you can move the original as well as the camera. If you are copying an original mounted on a wall, then the levels won’t help you. The way to get your camera positioned is to make the original square in the frame by moving the camera. This also requires patience.

You can use any lens to do copy work, but if you want to have a high quality copy, some lenses are better. You should probably avoid zoom lenses, they do not copy flat objects as well as fixed focal length lenses, and they often do not focus close enough.  One inexpensive alternative is 50mm lens. The best lenses for this work are macro lenses; they are designed to shoot a flat field. I use an older Nikon 55mm f3.5 macro lens. It does not have any automatic features when I use it with my camera, but those features don’t do me a lot of good with copy work. I have exposure information since I used the meter to set my lights. Auto focus often doesn’t work well on artwork, since there may not be enough contrast to focus on, and I don’t want to reposition my camera to focus. I usually place a coin or other object on the original to help me focus by eye with the macro lens. I can check my focus on the computer. Of course, when I am using a film camera it is a little easier to focus, since the viewfinder is designed for manual focus. One of the other problems with focus is that I have to stand on a stepladder to focus. I wouldn’t have to do that if I shot the original mounted on a wall, but it is much harder to get the sensor parallel to the original!

Practice, Test & Play

New house

I don’t suppose it’s news that I’ve retired, at least it’s not news to me. Also, I’ve moved to a place just outside of Santa Fe, New Mexico. I should say that life is very, very good out here. Anyway, that being said, I wanted to say a few things about what I’m doing photographically right now. As I’ve finished up the Courting Chaos project, closed the studio and stopped teaching, there are not a lot of things pushing me to do photography anymore, and, at the same time, I’m not trying to find any commercial work. That used to take a lot of time. What I am doing is working with black and white film and a few interesting cameras. I feel very good about doing this; it’s a kind of re-invention, or maybe, a return to my roots…

In order for me to get my film chops back, so to speak, I need to do the simple basic things that any photographer needs to do, especially when they aren’t being pushed form the outside: practice, play and test. I wanted to write a little about these things today. I think the first time I heard about photographers practicing was when I went to Nikon School. I was selling cameras in Santa Barbara at the time, if memory serves. What they suggested was focus practice. Back in the days of 35mm film SLR cameras focus practice was very important. I remember that they stressed learning to focus anywhere on the screen, not just using the split image. The fact was that they were right: focus practice does make you a better photographer. Of course, if you’re using an auto focus camera it’s different; you need to stay aware of the point or points the camera is focusing on, and how that fits your image. Also, modern digital cameras have so many menus and useful features that it helps to practice using any feature that you like that you don’t often use. One great thing about practicing with a digital camera is that you can take actual pictures to get feedback on your practice, practicing with actual film could get pretty expensive.

I’ve been working with a couple of cameras and with processing equipment, so I needed a lot of practice. It seems a little strange to me that the first camera I started to practice with was the Toyo 810M. Strange because this is one of the most difficult cameras to work that I’ve ever used. It’s an 8X10 metal field camera, so it weighs a LOT. As I mentioned above, working with film can get expensive, especially when each piece of film is 8X10 inches! I suppose I wanted to start with this beast because I knew that if I could work with that everything else would be easier. Then, of course, not only do you need to shoot this huge film; you need to process it! I’m using a Jobo processor. I got an 8X10 film reel that fits my tank and hold 3 pieces of 8×10 film. However just having this stuff doesn’t mean that you can actually load the reel in total darkness and get through a film run successfully. The processor makes it lot easier than running 35mm film in a metal tank: with inversion agitation every 30 seconds… However, it does help to have practice in running the processor. Also, there’s a lot of stuff you have to arrange to process film.  I had to build a darkroom and get plumbing to my sink! And, it’s important to know where you’re going to dry the film before you start! Every time you build a new darkroom, and I’ve built a few, there are a huge number of little details to be worked out.

But there are more details than just processing to worry about. Just composing an 8×10 camera is a little tricky. You’re working on an image that is upside down and backwards. It’s often difficult to see the image, especially if wind is blowing your dark cloth around. Depending on the lens the image can be tough to see. Lenses with smaller stops, and wide-angle lenses are tougher to see. I did get a new fresnel lens for the camera, which is helping. It’s also good to practice getting the camera onto the tripod; not only is the camera heavy it’s very awkward. I’ve purchased a couple of lenses for the big camera recently, so I needed to understand how they see and how they work. Of course, you can look through a lens and know a lot about the way it sees, but you know a lot more if you shoot film with it.

I’ve also practiced with a couple of medium format cameras. I’m trying to find a medium format camera that I want to stick with, but it’s tough to find something that meets my standards. First I’d prefer to work with the 6x9cm format. Obviously I like big negatives, but I also like that this format has the same ratio as 35mm full frame film. This cuts out a lot of popular cameras, like the Hasselblad (6x6cm), my beloved Mamiya C330 (6x6cm), the Mamiya RB and RZ (6x7cm) and the Bronica, Pentax and more. In fact, most of what it leaves you with are press cameras made in the late 1950s and 60s. Actually not such a bad thing, most have rangefinder focusing and they’re pretty cheap. I’ve tried out the Koni-Omega, the Horseman, the Graflex and the Mamiya Press. All of them have their advantages, but right now I’m using the Mamiya. There are a couple of reasons: first the Mamiya has the widest lens I can find for a medium format press camera, a 50mm f6.3. Second, some of the Mamiya Press cameras can use Graflex roll film backs. This is kind of rare, but I have one. I like this because I have a bunch of these backs, and they fit other things I own. Also, they are easier to find than most of the other roll film backs. The actual range of lenses is probably larger than most of the other cameras I mentioned, but the Horseman could take many view camera lenses. The Mamiya has some back movements, sort of like a perspective control lens for a digital camera or a standard view camera. The back also allows some macro work not available with the other cameras. In fact, one of the reasons I don’t like the Koni-Omega, is that it doesn’t have close focusing. Of course, you have to put on a ground glass to focus, but it’s great that the camera has this. Still, there are problems… These are all metal cameras, so they’re bulky and heavy. With 4 lenses my kit weighs almost 25 pounds. Second, these are old cameras and they often need maintenance. One of the things I’ve had to do is re-calibrate the rangefinder, a job which requires patience. You can’t just run to your local camera store and buy one, you’ll be searching for a while on eBay.

I’ve needed to practice with the Mamiya quite a bit. The rangefinder isn’t very contrasty, so you need to work with it to get the hang of it. The viewfinder is separate from the camera lens, so you need to learn about how the camera actually frames. In addition, the wide-angle lenses require auxiliary viewfinders, which is a little annoying, maybe a lot annoying… I needed to practice changing the lenses, too. If I forget to put the dark slide in, I’ve ruined a frame. One other thing that takes getting used to is that there isn’t any double exposure prevention. You need to decide if you’re going to wind the film before you shoot or after, and stick to it! Of course the upside is that you can change film holders in the middle of a roll. Perhaps it just that I’m a person who likes to d things the hard way. I believe there is evidence for that.

While I’m discuss getting my chops back with various cameras, I should mention the Brooks Veriwide/Graflex XLSW camera. Both cameras were designed for the 47mm f8 Schneider Super Angulon. The 47mm S.A. was designed as a super wide-angle lens for 6X9cm. I really enjoy working with wide angle lenses, just in case that wasn’t evident. The thing about this camera is that it’s quite simple, lens, with built in shutter; viewfinder; focusing helical; and Graflex roll film back. The result is a fairly small, reasonably light camera, with a huge angle of view. Really nice. Of course, it’s scale focusing, no rangefinder. I suppose I could use the Graflex ground glass back, but that would make the camera much slower to use. The other drawback is that the lens is f8, and doesn’t entirely hit its stride until f16, well no one is perfect.

I have several other cameras that I still need to practice with. I’ve done almost no work with my Cyclops camera, which shoots 120 film with a moving lens. It makes very large panoramas. Speaking of very large panorama shots I have a Korona 8×20 camera that I need to drag out soon. I really should do a shot in the next few days so I can say I used it during August, after all the date is 8-20. I haven’t used the 11×14 camera since I closed the Courting Chaos project, but I did use it a lot for that project. If you’re counting my cameras there are a lot more… Keith Richards has three thousand guitars, so I have a way to go.

Now clearly all of this practice is well and good, but practice has its limits. The limits of practice are discovered by testing. Some testing is very easy to understand: all the lenses I’ve been using have leaf shutters, which are inaccurate. Leaf shutters are mounted in the middle of a lens rather than near the film. In addition all old leaf shutters are inaccurate to some degree, and all of mine are old, much like myself. There is actually a phone app that does a pretty good job of shutter testing, if you have old shutters you should find the app. I’ve know a lot of people who do obsessive processing testing. This used to be extremely important. Even as recently as the 1950s and 60s many film emulsions were thicker, which changed the way films recorded light a lot! This has a lot to do with why Ansel Adams and others developed the Zone system. Film recorded low light differently from middle grey and highlights blocked up. There are some films which will still react this way, if you want to experience greater frustration. Modern black & white films, like Kodak T-max and Ilford Delta will handle the highlights much better than say Super-XX; so exposure is easier to manage. In addition, most photo papers are multi-contrast which gives the printer much more control over the way the print looks. Alternatively, you can scan a negative and manipulate it in Photoshop, which gives you much more control over the outcome! You can make a new enlarged negative with a printer and make a variety of different kinds of prints, customizing your negative to fit the printing material. So my goal in testing film is to get a negative with a long scale, many tones between black and white. I’m also looking at the graininess of the film and it’s resolution. So far I like the Ilford Delta 400, but I do want to check more films. While I’m looking at film resolution I’m also examining the resolution of my lenses; all lenses are not created equal. At some time I need to do some writing about the way lenses affect pictures. Many people are fiends for “sharp” lenses, however many people interpret contrasty lenses as sharp because they make images that “pop”. Here’s the thing, if you do post processing of your shots with Photoshop it can be better to have lenses with resolution that you like and control contrast in post. I’ve found that I like Goerz lenses, and I have a bunch of them. More on lenses at another time.

There are some basic tests I shouldn’t ignore: is your camera light tight? Are your film holders light tight? Some of mine were not. It’s important to know where the weaknesses of your gear are. One more test: can you carry the damn camera bag and the tripod without too much suffering…

Here’s the thing, we do all this so that we can PLAY. If we get too caught up in technical details that we forget that photography is way of communicating and documenting. If we aren’t doing any shooting that all the gear and all the knowledge don’t matter. Play means both expressing technical skill, craft, and experimenting. If you don’t make mistakes; don’t walk outside your comfort zone you aren’t really doing anything new. If you don’t express yourself with good craft than people won’t be able to appreciate your images.

Shutter Hacks 2

So it’s been a long time since I last updated this blog. I’ve done a lot of personal projects since I updated this blog. The biggest one has been moving to New Mexico. I’ve also done a number of equipment related photographic projects in the last year, which I am going to add to this blog as time goes by. This is the first one of those, and in some ways it’s just an extension of the last blog post I did. You may remember, or you can check below, it was about shutters and lens boards for large cameras.

New Photography from Taos San Francisco de Asís Mission Church #1. Made with the Toyo 810M and 6 ½ inch W.A. Dagor.

The two elements that have the most do with how your final images are captured, are first, the lens that makes the image, and second the way in which you record the image. Many lenses are designed to have as little character and to be as sharp and contrasty as possible, but that’s not true of all lenses. Some lenses are designed for soft focus, some lenses are designed primarily to bring the image closer or to give you a wider angle. Many lenses have lower contrast and more flare. Modern lens design is often more concerned with contrast than with sharpness. The human will often see contrast and saturation as more graphic than actual detail. Also, some lenses are just not very good. Many older lenses, while they may have flare or other defects, can make very compelling images. Some modern lenses have been designed for digital cameras that exhibit these properties: check out Lomography.com for examples. The lens you use may have more effect if you’re working with a large format film camera; and you’ll have more lens choices.

 

Regarding recording the image, if you’re recording it in digital then the simple thing is how much resolution do you have? But if you’re recording it in film, the size of the film and the characteristics of the film will have a huge effect on your final image. The resolution of the film, whether the film is color or positive transparency, or black and white negative film, all these things have a tremendous amount to do with your final capture.

In order for the lens and film (or sensor) to function well, you need a number of controls on your camera. You need to control how much light finds the final capture area, whether it’s film or digital, and that’s done by blocking some of the light in the lens with a diaphragm (aperture) and by using a shutter (shutter speed). You’ll need to focus the lens by changing the distance between the lens and the film and of course, you need to keep everything dark between the lens and the capture area.

So a camera may be quite simple: just a film holder and focus. With large format cameras the shutter is usually mounted in the lens, as is the diaphragm. Many large format cameras are little more than a platform for the assemblage of parts. Many cameras are much more complex, particularly digital cameras, which will have the sensor and shutter and meter and viewfinder and electronics built into the camera. One advantage of a large format camera, not only can you change the focus of the lens, but you can change the geometry of the camera: the camera allows you to change whether the film plane and the lens plane are parallel to each other as well as the distance between the two. Sometimes simplicity offers more control than complexity.
All of this means that you can modify large format cameras. You can create or customize cameras that give you special abilities or enable you to use special lenses or enable your lenses to do things they might not otherwise have done. You can put different sizes of film on behind lenses that were designed for something else. And all of this can be very creative, and it can be fun! It can enable you to make images you couldn’t otherwise make.

The Sinar shutter mounted onto a Toyo Bellows lens hood. You can sell all the shutter speeds on the side. It’s mounted sideways to keep the shutter control away from the rails of the bellows lens hood.

In the last blog post I talked about changing lens boards and mounting different lenses onto multiple large format cameras. I showed how I made a make lens board converter to enable me to fit a Toyo lens board on my old 8X20 Korona view camera. I also showed how to mount an external shutter, called a Packard shutter, on to a bellows lens shade. This puts the shutter in front of the lens. Packard shutters are air-driven shutters and they’re incredibly useful, but they have only limited control. In this post I’m demonstrating two more shutter adaptations: one is using a shutter from a Sinar camera and the second one with a Packard shutter.

A side view of the bellows lens hood and the shutter. The adapter from the lens hood is glued to the lens hood. The original purpose of the lens hood and the barn doors is similar.

Sinar are made wonderful view cameras, very complex, with very precise levels of control. Very fine Swiss workmanship. They were some of the finest view cameras you could buy, but they were also some of the most expensive view cameras you could buy. They made some really, really interesting accessories. One of the things they made was a shutter designed to fit into the camera. This shutter was way better than your average Packard shutter because this shutter what had accurate shutter speeds from 1/60 to 30 seconds. As time went by their shutters evolved into electronic devices that could only work with Sinar cameras. The shutter I adapted was designed to work with the older Sinar Norma cameras. It is a completely mechanical shutter.

The Sinar barn doors, before disassembly.

Rather than use the magnetic strip I used to hold a Packard shutter to my bellows lens shade, I used the mount from a Sinar barn door attachment, which I put on the front of a Toyo bellows lens shade. Now it works with any of the cameras that I’ve already adapted to take the Toyo bellows lens shade: my 8X20 Korona camera, my 11X14 camera, my Toyo 810M and Toyo 45C. Not only will it fit a lot of cameras, it will fit a lot of lenses. You can see how this comes together in the pictures associated with this particular post. The Sinar shutter requires a cable release with an extremely long throw, much longer than a regular cable release. This is because the cable cocks the shutter as well as triggering the shutter. I’ve found that the only cables that work are the ones Sinar built for the shutter.

The whole assembly mounted onto my Toyo 810M. Note the Sinar cable release.

Another project that I want to share here is a shutter I attached to a Toyo board that was originally made to fit adapt the Speed Graphic lens boards onto the Toyo cameras. Many of my lenses are mounted on the speed graphic lens boards since the boards are common, inexpensive and small.  The Packard shutter mounts directly behind the Toyo board. You can see this in the pictures. This is a smaller Packard shutter. There’s a pipe which attaches the air hose through the shutter. It’s a very handy item.

The front of the Toyo/Packard board. The tube in the upper right is for the air hose.

The back of the Toyo/Packard lens board. You’ll notice the tube from the front is attached with rubber air hose to the piston.

Both projects are also shown with the diaphragm adapters that allow you to hold lenses that aren’t mounted onto boards and don’t have retaining rings. This all makes for very, very flexible lens mounting system. You can put practically any lens on the front of your view camera, even lenses that were never designed for cameras.

The Toyo/Packard board with a lens attached. I’ve used an old diaphragm holder to attach the lens.

I’ll be describing several more projects in upcoming posts, including a tour of my new darkroom. Also, I will be selling a number of items that I no longer need. So, if you watch this blog you may find those items listed; and they will cost a little less money here than on eBay.

So if there’s anything that you’re particularly looking for you might let me know send an email to John@Siskinphoto.com, thank you very much for your attention.

Lens Board Hacks for Large Format Cameras

I’ve been teaching people about view cameras for a long time. I used to tell people it was like a cross between an erector set and a camera. You can put it together in whatever way you want. I also used to tell them that it was a simple camera; the thing is simple doesn’t mean easy. An ax is a very simple tool, but if you need to cut down a tree, I guarantee you that a chain saw, while more complex, will be easier…

 

The view camera is essentially three parts, the lens, the bellows and the film holder. The rest of the camera is there to make it possible to fit these parts together in the best position for a specific photograph. I’m going to be discussing how the lens is mounted on the camera in the rest of this post. Almost any lens will fit on almost any view camera. Brands don’t matter because lenses are fitted to boards which fit specific cameras. There are no electrical contacts, rangefinder cogs or complex bayonets in this system, only rectangular boards. These boards are designed to fit on a camera so that no light can leak around the board. Many recent manufacturers use metal boards with a sort of lip that fits the camera, but may versions have been used over the years. This s the problem: most cameras use a board that only fits that brand, or at most a couple of brands, of camera. In fact, many camera companies use different boards for different model cameras. While this doesn’t mean that you can’t exchange lenses between different cameras it does become a pain in the neck. In order to mount a lens on a different board you generally have to unscrew the rear elements and remove the retaining ring before you put it back together on another board fitted to that lens.

 

If you only have a couple of lenses and a couple of cameras this isn’t intolerable, but for me it’s getting out of hand. I have a couple of dozen lenses and five cameras I might use them on. Since each lens might be used with any of the cameras this can mean a lot of lens boards. I’m not the first person to create conversion boards, in fact, many of the camera companies build boards to fit boards from other cameras. However, a couple of my recent cameras, my 11X14 and 8×20 camera, are older and no conversion boards exist. Also my main lens boards, the 6X6 inch Toyo board, is too large to easily fit to these cameras. To compound the problem these two cameras don’t take the same lens board. So, I want to show you how I solved this problem. In addition I want to show you a way to use lenses that don’t have a retaining ring and lenses that don’t have a shutter.

 

The basic plan, which I’ve illustrated below, is to take a lens board that fits the new camera and attach it to a lens board that fits a Toyo camera. You’re going to put them together front to front, with a little space between. The space allows for the boards to be connected to the camera. Then you can take the center piece of the front standard and mount it to the Toyo board. Since the standards on Toyo cameras, and several other cameras, are the same on both the front and back this works well to give a place to attach any lens mounted on a Toyo board. I should also point out that the standards on Toyo cameras, at least older ones, are pretty fragile, so it’s possible to get the part you’ll want off a broken camera.

THIS PROCESS REQUIRES POWER TOOLS. BE CAREFUL. USE EYE PROTECTION. IF YOU HAVEN’T USED THESE TOOLS BEFORE PRACTICE ON UNIMPORTANT MATERIALS.

01: This shows my new Korona 8X20 camera. The lens board I’m converting is mounted on the camera.

 

02: The wooden lens board for the Korona and a metal Toyo board. I want the Korona to take Toyo boards.

 

03: After I’ve outlined the hole I want; I drill holes around the edge of the hole. These holes make it easier to control the Dremel tool.

04: The Dremel set up. The bit cuts to the side. The black collar makes it easier to control the Dremel tool. BE CAREFUL, the Dremel is tricky to use.

05: Cutting the hole with the Dremel tool.

06: I use the hole in the wood lens board to size the hole in the Toyo board.

07: I’ve used the same process as I did on the wood lens board. Holes first then the Dremel too. The metal board is more difficult to cut than the wood board. BE CAREFUL-USE EYE PROTECTION!

08: The metal board has sharp edges. I’ll use the Dremel to sand them smooth

09: I’ve drilled holes in the edges of the Toyo board. Then I’ll use those holes to drill hole for the bolts into the wood lens board. I’ve placed washers in the space between the boards. If you just screw the two boards together you won’t have space to mount them on the camera.

10: I’ve assembled the two boards. I’ll check this assembly on the camera Before I Glue The Parts!

11: I’ve put a bead of the glue onto the wood board. I use Ultra Black Gasket Maker Glue. Basically it’s black silicone sealer.

12: I’ve put the glue into the gap. Use a lot of glue. You don’t want light leaks. This is a messy step.

13: This is the part I salvaged from a broken Toyo standard. I had to fill a couple of screw holes with the same Ultra Black Gasket Maker Glue. I use the same part on my 11×14 camera.

14: the assembly mounted on the 8×20 Korona camera.

15: My Schneider 270mm Wide Angle G-Claron f6.3 mounted onto the camera!

View camera lenses are connected to lens boards with a threaded ring machined on the outside of the lens. These threads mate with a ring called a retaining ring. This is a simple system which works well until the retaining ring is lost. If all these retaining rings had been standardized to just a few sizes losing a ring might not be a problem. Unfortunately there are at least dozens of different widths and thread counts and pitches, so it’s impossible to just order a replacement. Generally you’ll have to have a new retaining ring custom machined. This is expensive; if you can find a machinist with the needed skills. However there is a fix! Many years ago, a sort of universal lens holder was made. This used a variable diaphragm, like the aperture in a lens. These diaphragms were made with very stiff blades, which could be locked in place. These are generally available at eBay, but they are pricey. Expect to pay from $200 to $500 for a good one. You want to be careful to check how large and how small the diaphragm adjusts, so you can be sure it will fit as many lenses as possible. Use terms like adjustable large format lens diaphragm to find one on eBay. Keep in mind that you need to be sure the lens is probably seated and locked in place before you put the lens on your camera.

A1: The lens mounting diaphragm on the camera.

A2: An old brass lens on mounted to the 8×20 camera.

In addition to lenses that don’t have a retaining ring there are also a lot of lenses that don’t have a shutter. Of course you can use a lens cap if you’re working with a long exposure, but if you want more choices it’s good to have a shutter. You can have a machinist install your lens in a new shutter, but this is quite expensive and requires a very good machinist. If you have as many old lenses as I do this can be a daunting prospect. There is a way around this problem as well, but it isn’t as controllable as a modern leaf shutter. The solution is a Packard shutter. Strangely enough these are still being made! You can find a new shutter at packardshutter.com, or you can find used ones on eBay. These are air driven shutters, which means that they’re powered by an air bulb that you hold in your hand. In fact these air bulbs are the reason that most shutters have a B setting, b stood for bulb. With these shutters you can hold the shutter open as long as you want, or open and close the shutter in about 1/20 of a second. It’s important to stress that that fast speed is extremely variable. These shutters are often mounted inside a large view camera or on the back of lens boards. I’ve arranged one to fit on the front of a Toyo compendium lens hood. This works very well for a couple of reasons, first I can use a very large Packard shutter that wouldn’t fit into my camera. Second, I can use the same shutter with several cameras. The compendium lens hood protects my film from being exposed by light from the side of camera. It’s also nice that the compendium hood fits onto the part of the front standard that I used as my lens board converter! This means that I can mount the same shutter assembly on several cameras, including some that are quite old.

B1: The Toyo standard has mounting holes for a compendium lens shade. The shade is mounted in this shot.

B2: I’ve moved the compendium shade in front of the lens. I put magnetic strips on the front of the shade. These strips are holding the Packard shutter in this shot.

B3: The Packard shutter is open in this shot. Now I can use the Schneider G-Claron on the camera!

About Lenses #1

So this post is sort of a plan or, if you prefer, a work in progress. A couple of days ago I put a post on Facebook announcing a series about lenses; this is the beginning. The idea is to have place where there will be links to the other posts and to give a sort of outline for the project. I’ll update this post as the project takes shape.

The first thing you should know: if you’re looking for advice about what lens to buy for your dSLR you may just want to pass on this whole thing. There are a lot of places you can get that information. This series is about understanding lenses and lens design. It may help you choose a lens for a dSLR, but the intent is to help you choose lenses for large format film work. Regardless it will help you understand how lenses work, and that can’t be a bad thing.

I was shooting with my 11X14 camera yesterday. I made a dozen negatives and shot with four lenses: a casket lens-focal length about 230mm; a Schneider Dagor-14 inch focal length; a Goerz Artar-focal length 12 inches; and a Goerz Gotar-13 inch focal length. The thing is, the focal lengths are very similar on these lenses, so there must be other reasons for making choices about which lens to use. When shooting with a small camera one of the first reasons to make a choice about a lens is the distance you’ll be from the subject. If you are closer to a subject you build more shape into the image, while if you’re further from a subject the image will feel flatter. People discuss this as if the lens changes the perspective. But that’s not true-it’s how far the subject is from the camera. If you shoot a persons face from 10 feet away it will always look flatter than if you shoot the same face from a foot away, regardless of what lens you use or how you crop. Distance from the subject is important to my work, but many other things influence my lens choice. First I think about coverage: you need a lot of image to shoot an 11×14 inch camera. I have a lot of lenses that would just make a circle in the center of the ground glass, and I have a lot more that won’t be sharp over the entire frame. The sense of sharpness and how the un-sharp image feels is critical to conscious lens choice. It’s like a painter picking a brush; even a house painter uses different brushes for different tasks, even more so for a portrait painter.

There’s more to the character of a lens that just sharpness. Contrast is also very important. The human eye interprets contrast AS sharpness. As a result of this modern lenses are always designed to maximize contrast, and that is generally a good thing. Maximizing contrast was particularly important before Photoshop because it was very difficult to control contrast in color printing. One of the things that improved contrast, perhaps more than any other factor, was lens coating.

Shot with 28 cm and back elements of my C. Bethiot casket set. An un-coated lens.

So this is a quick discussion of some of the topics I’d like to explore.

History of lenses. Lens construction pre-dates photography by at least a couple of centuries and possibly millennia. Lenses added to human vision. The thing is that since the human eye sees only a small field at any moment you don’t need to make lenses that are accurate over a large field since a person can move the eye or lens to compensate. Making photographic lenses that would cover a large area, at one time, was an early challenge.

Soft focus lenses. There is a difference between spherical aberrations and chromatic aberration and just poor focusing. I’ll also spend some time on soft focus filters. Many lenses have been specially designed to make soft focus images.

Flowers Wrapped in Newspaper-Shot with a Bausch & Lomb Plasigmat. This is a double exposure at two different apertures, which allowed me to selectively choose what was soft and sharp.

Process lenses. These are specially designed to meet the challenges of making printing plates for off-set presses. They are highly corrected for color and field flatness. Using them offers some special opportunities and challenges. I have several of these lenses that I use with my 11×14 camera.

Shot with a Goerz 12 inch Red Dot Artar on my 11×14 camera. Processing effects do not reduce the great sharpness and contrast of this lens.

Lens aberrations. These include pin cushion distortion, barrel distortions and coma.
Classic designs. Of course there is the Tessar from Zeiss, and there are so many more: Dagors, Dogmars, Angulon, Biogon…
Casket lenses and convertibles. Large format lenses are basically fixed focal length lenses, but many large format lenses have been designed that offer multiple focal lengths. I wrote an article for View Camera some years ago about DIY casket sets. You can download it here: www.siskinphoto.com/magazine/zpdf/LensAssembly.pdf

Shot for an article in View Camera about DIY soft focus lenses. This uses Kodak Portra lenses (add on lenses) instead of a lens designed to be used alone.

This whole thing will go on, but if I don’t post something now I may never get started.

The show is going to be on display until the end of November, so you still have a chance to see the real photographs. I say real photographs because looking at an online version of an image adds a sameness to all images. On your phone or monitor images always about the same size and the color is always affected by your monitor. These two images are BIG, 30 inches wide and about 40 inches tall. If you care about photography its a really good idea to see actual photographs, not just digital versions. I used 3 types of prints in the show: silver gelatin prints, cyanotypes and a couple of Kodak color glossy prints. As I mentioned in the last post you can visit this previous post for more information about print types: https://siskinphoto.com/blog/?p=2243. The other images, the silver gelatin and the color glossy images are posted as parts 2 and 3 of the show. The Silver Gelatin prints are at: https://siskinphoto.com/blog/?p=3571. The cyanotype images are at: https://siskinphoto.com/blog/?p=3630


The show has 41 images up on the walls; these are the two Kodak Color Glossy images. These are machine made images. I could print a hundred of them, all exactly the same, by pushing a button. The images are for sale. The images are about 30×40 inches and mounted on Gator board. The price is $350. The price includes shipping in the U.S. For this and all the other images please contact me directly at john@siskinphoto.com to arrange the purchase.
