Sooo... there don't seem to be any easy, good instructions around here for this. These are super easy, and to me, easier then the whole oatmeal box thing.
materials:
film canister(BLACK)
2x2cm piece of aluminum from soda can
black electrical tape
needle
exacto knife or some sharp scissors
First, take your film canister and cut a square hole into the side. The hole should be about 1x1cm, definitely not bigger then you aluminum piece. Then, take your needle and gently poke a very small hole in the center of the aluminum piece. Using the black electrical tape, tape the aluminum piece to the outside wall of the canister, the pin hole should be roughly over the middle of the square hole in the side of the canister. Viola! Pinhole camera. If your images are blurry your pin hole is too big. Think very small.
Tips: Position the square hole about halfway between the top and the bottom of the canister.
Make the hole very small.
You can use plain
photographic paper(from photography supply store) cut into small squares or small pieces of
ortho litho film so you can blow the image up as large as you like.
Place the cut paper, emulsion side up, inside the canister, against the wall opposite the hole. Pop the top on and you're ready to go, just be sure to cover the hole with your finger until to position the camera. The exposure times on these will be very
long in normal lighting situations. They will be even longer with ortho litho film, like 30 minutes.
