I was bored this afternoon, so I thought it would be fun to make a pinhole from one of the many 35mm film cnas that I had ahgning around. So I made a small hole in the side witha thumtack, taped a piece of tinfol over as a shutter, and taped a piece of tinfoil in the front as a shutter, and put some Lucky SHD 100 (cut down from 120 format) inside. I exposed for 4 seconds - ish (was just a guess on my part). The image, once developed (5m 30s in D-76 at 21ºc, right in the can) and fixed was a quite thin (longer exposure next time), but surprisingly sharp, considering that it was taken with a film cat, with my knee as suport instead of a tripod. Has anybody else tried this, or anything else cool for pinholes? I think that its amazing that decent (and sometimes absolutely incredible) pictures can be made with such unbelievably primative equipment. Any ideas?
