Pinhole examples;
Steps in creating a pinhole camera;
1) Gather materials. – Box, photo paper, thin piece of metal like a can or brass shim, tape, xacto knife, needle, sand paper.
2) Make the pinhole by poking a tiny hole in the brass shim with a needle and sand it smooth. Trim the shim so there is a little space around the hole.
3) Make camera box. – Use a light proof box and paint it flat black then cut a small square opening in the box for the pinhole to go in.
4) Put in pinhole and make shutter. – Tape the pinhole behind the square opening and make a shutter which is just a flap that covers the pinhole from outside.
5) Load the photo paper. – HAS TO BE DONE IN COMPLETE DARKNESS. Tape the piece of photo paper across from the hole and put the lid on.
6) Taking a picture. – Point the camera at what you want to shoot. (Best when bright and sunny) Open the shutter for 30 – 4 minutes then close, make sure to be perfectly still. Then take to darkroom and develop.
