When I was in 8th grade photography, we made simple pinhone cameras out of peanut cans. All you have to do is poke a hole in the front and put in photosensitive papaer. By the way; do you know how to make photosensitive paper, or where to get instuctions for making it? | ||

One of the easiest and cheapest ways is called Cyanotype, and is used to make "blueprints". You make a solution of ferric ammonium citrate in one bottle, and a solution of potassium ferricyanide in another bottle. The exact proportions are not critical. When you want to make the paper, mix equal amounts of these solutions in a dark or dimly lit area, and soak the paper in the mixture. You can use the paper wet, or allow it to dry. It is not as sensitive as silver halide papers, so you can be less worried about exposure to light for small amounts of time (you don't need a darkroom), but the exposure will take a lot longer. When the image is complete, rinse off the paper in water to remove the unreacted solution. Your image will appear in light blue. Because of the low sensitivity, the easiest way to make an image is to place objects (keys, leaves, whatever) on the paper and set it out in the sun. If you Google for ("ferric ammonium citrate" "potassium ferricyanide") you will get lots of recipes and advice. | ||
