Kodachrome at Eastman House

Filed under: Film Technique,Lighting Technique,Looking at Photographs — John Siskin @ 8:15 pm

I wanted to post some information about my experience at The George Eastman House in Rochester. It’s been over a week since I got back, so I have had a chance to think about things a bit. I really wasn’t very interested in taking pictures of the house, so if you want to see the place, visit the site. The collection is huge and only a small amount is on display. You can see much more of the collection by making a request. I wanted to see large format Kodachrome, and the staff were kind enough to let me see dozens of example of 8X10 Kodachrome. Most of this blog will be devoted to what I learned. I wish I had some Kodachrome images to attach to this blog, but the scanner is still missing from the move. Besides you should look at original Kodachrome transparencies, the image on a computer is not the same. The computer makes everything the same size and removes other individual characteristic of images. So I’m just attaching a couple of food images.

Kodachrome was developed in the Kodak labs by a couple of musicians named Leopold: Mannes and Godowsky. The Kodak labs were run for most of the twentieth century by C. E. K. Mees. The Kodak lab was arguably the first industrial research lab. Kodachrome was a huge step forward in capturing color. The previous methods used a filter over a single emulsion, which is very similar to how digital cameras capture color. Kodachrome used three separate emulsions that captured individual colors. This captures much more detail. In addition, with a Kodachorme image, the color went where the silver molecules were. As a consequence Kodachrome images last much longer than other color processes. This was something I wanted to see.

Most of my first color shots were made on Ektachrome color film in the middle seventies. These images are beginning to fade. The Kodachrome shots I saw at Eastman House were from the fifties. The color was as vivid and as crisp as if they were made yesterday. As with other Kodachromes that I’ve seen, the images had no visible grain. Certainly, in large format sizes, Kodachrome was capable of capturing more information than most current digital cameras. of course you wouldn’t see this on print sizes less than 11X14, and probably not on print sizes  less then 20X30 inches. Unfortunately all sizes of Kodachrome, and processing for Kodachrome film, are discontinued.

I also learned a lot about shooting food. The images I saw were made by Nickolas Muray. Almost all of them were images of food. I was interested to see how much hard light he used to make his shot. The food had shape and sparkle as a result of this. I was also interested to see the design of the shots. Many of his images included items that a current stylist would never use. These shots were probably made in the fifties and early sixties and our ideas of how food should look have changed. It must have been difficult to shoot the food for several reasons. 8X10 cameras heed to shoot at a small stop, perhaps f64 or smaller, which means you need a lot of light. He used quartz lights, so heat would have been a consideration especially with food. He had no Polaroid proofing, so I don’t know how he tested his lighting and exposure. Perhaps he set up the day before and ran a test sheet of film overnight. It was really a pleasure to look at the very fine work that Nickolas Murray shot.

Projector Blues

Filed under: Film Technique,Lighting Technique — John Siskin @ 10:38 pm

Blue LightYears ago I went to a lecture about lighting, I think it was put on by Kodak. The photographer had these awesome little lights, hot lights, with built in baffles that allowed his to precisely control where the light went. Similar to working with barn doors, but with a harder edge, and more control. The lights had lenses so your edges could be harder or softer. I thought these lights had to be the best thing ever for tabletop work. The only problem was that I didn’t own them.

I had already seen work by Moses Sparks that used a slide projector to project images on top of the human body. You’ll understand that this was in the dark ages before Photoshop. So it suddenly occurred to me that I could get the precise lighting that I wanted with the slide projector. You can see an article about doing this kind of work, with film, at this link.

When I first started working with digital cameras one of the hardest things to give up was the creativity the slide projectors gave me. Because I could control the placement of the light, project color and images, and control the brightness of the light, the projectors were awesome tools. Digital cameras, the several I have owned anyway, can’t keep the shutter open for ten minutes, while you turn on and off timers.Red Light

Recently, I got an upgrade firmware package for my camera that improved the way it works with long exposures. While it is not a ten-minute exposure I can now do a shot at one second, before I had noise problems with anything longer than 1/20th of a second. So I can now use the projector to add special lighting effects to portraits and other shots. Really a great thing!White Light

A Basic Understanding

Sky & Sun

Sky & Sun

I was talking with a few old friends who are also photographers. Both of them were complaining about younger photographers who don’t know anything, as they would have it. Now neither of the guys teaches or interacts with new photographers in any regular way. One of them explained to me that you couldn’t really learn Photoshop without experience working in a chemical darkroom. I am older than either of these guys and I don’t believe any of this. The reason is that I actually interact with new photographers all the time. Teaching here at BetterPhoto will do that.

Inspired by my old friends, I want to go over the basics. Cameras, regardless of whether they are digital or film share some characteristics, these are like the language of the machine. For instance whenever you use a variable size aperture in a lens, what we refer to as an f-stop, you introduce changes in the distances that are in sharp focus. We call this depth of field, not really a very good name.

Speaking of bad terminology, I will start with the word STOP. Now we all know what that means, but not moving has nothing to do with the term in photography. In photography it means a relative change in exposure: if you have twice as much light in your shot as you did previously you have one stop more light. It doesn’t matter if the change is caused by changing your aperture or shutter speed or because the sun cleared the horizon, if you have twice as much light that is one stop more light. If you have four times as much light that is two stops, well you only doubled the amount of light twice. If you have 1/8th as much light you have three stops less light, maybe the sun just went under the horizon.

I know that a lot of people don’t want to talk about math, but it is the key to controlling the pictures you take. You can take all the pictures you want on automatic, but if you want to MAKE pictures you need to understand the controls on the camera.

Memory

Filed under: Film Technique,Photography Communication — John Siskin @ 10:18 pm

Hand in HandThis week I want to talk about making pictures and taking pictures. An incredibly large percentage of the population will take pictures in the next year. They will point the camera at something and press the button. People do this because we have a real need to capture the stuff of memory and keep it with us. This is a very personal communication, from me to me. Like a personal time capsule. If I were to take out my memory photos and show them to you, they wouldn’t mean as much to you. We all take these pictures, written in the language of our own experience.

A photographer is called to do something more, to make a picture. To use the tools of craft and the skills of design to make an image that speaks to many, if not all. So a photographer need to have a command of the language, which is a product of craft, and a sense of how to shape an image, which is design. What separates a photograph that is made from one that is taken? In addition to skill and design, clearly intent is an important aspect. You need to think the image through, how are you going to make that image communicate?

The shot I attached this week works on both personal and on a more universal level. I was working with the hands and the watches and watch faces to make an image that would create a feeling of impermanence and transition. I think I accomplished much of that. The image is also personal, because I remember the experience of making the image. While this is often a part of an image for me, here it is a larger part. I did some things with the camera, and the processing, that I really only did successfully this one time. This shot is made on one piece of film. I actually did a double exposure and did a controlled solarization of the film! So, at least for this photographer, it is possible to make a photograph and still have it be personal.
