Developing and Printing

Pinhole Photos

Most of the fun with oatmeal-box pinhole cameras happens in the dark. The actual photographs are made in the darkroom, and they are 5 x 7 inch prints, not little wallet-sized pictures! A few supplies are needed for the darkroom, in addition to the safelight mentioned earlier. Here's a list:

These chemicals are common darkroom chemicals for black and white print developing. They are not toxic under normal use but injestion is not recommended. Read all manufacturer's labels and cautions before using.

Developing the "Paper Film"

Here you see the negative of a hand in a pile of leaves as it develops in the developer tray. Under the safelight, remove the exposed film from the camera and place it in the developer tray. Gently rock the tray so that a wave of developer washes back and forth across the film. When it looks dark enough, pick the film up by one corner and let it drip for a few seconds. Then place it in the second tray, the stop bath (or water, if so desired.)

Again, rock the stop bath tray for about ten seconds (this is called "agitating"), lift up the negative and let it drip, then place it in the fixer tray. Agitate the fixer tray for at least two minutes. Fixing the image is very important: the fixer dissolves out any silver which hasn't turned black, so that years from now, the picture won't turn yellow or some other unwanted color. Sometimes improperly fixed photographs just fade out, as if they were bleached by time. After a minute of agitated fixing, it is OK to turn on the room light--after first checking to see that the photographic paper is covered!

The last "wet" processing step is to wash the photographic paper in clean, room temperature water for about four minutes. This step is very important, too, because if any fixer is left in the paper, it will act like a bleach and cause the photographic image to fade over time. Room temperature water is important because water which is too hot or too cold can damage the layers which make up the photographic paper. Last, pat the paper dry with paper towels or with a clean cloth towel and set the paper on a clean space where it will quickly dry.
