Remember why you like pinholes...

—There is something so deliciously low-tech about being able to build the device that creates a photographic image. I’m actually thinking of ways that the photograph can be displayed inside or wrapped around the device that took the image.

—Pinhole cameras can “shoot” straight to paper, thus creating a unique artifact/image (albeit a “negative” or reversed one) as opposed to traditional film which can be printed millions of times. Pinhole photography can be non-mass mediated photographs.

—Negative images are cool ways to bring out unseen aspects of textures. So many things look interesting though familiar when reversed (tree bark, salt stains on asphalt, concrete…)

So…

I’ve saved oatmeal containers and round cardboard containers of various diameters. I’ve also saved several boxed of different sizes. (If I understand correctly) the diameter of the round boxes and the thickness of the rectangular boxes is responsible for the focal length—and on the round containers, the length changes, hence producing that weird “bent” image.

I have sprayed the inside of these boxes with flat black paint to keep stray light from bouncing around. The paint also helps make the chamber light-tight.

I have harvested little scraps of aluminum from pop cans, flattened them the best I could and taped them to the front of the cameras. All that’s left is to poke the actual pinhole. I found on-line a list of the f-stop produced by various sized pins. (Who knew there are different sizes of pins?)

The first stage is just to make a bunch of images under relatively controlled conditions. I want about a dozen cameras for this test. I need the chemicals and to reclaim enough space in the basement to set up the “dark” room.

Later stages include alternative developers (like coffee and vitamin C.) And I’ve also been working on a steam-punk pin-hole camera that uses a flatbed scanner instead of the photographic paper.
