This is a great tutorial on how you can build your own multi shutter pinhole camera using old film canisters and a metal can. Very inventive I must say. The images taken with this sort of camera blends together different scenes in a very organic (see examples) way that many people can only achieve these days using a graphics program like Photoshop. Does anyone still remember the bad old days when trial and error was the only way to do such photographic manipulation?
