Instr03 SmallAlspix’s how to on making a matchbox pinhole camera “My first couple of 35mm pinhole cameras attempted to be panoramic, wide angle jobbies but this time I thought it would be nice to get back to the classic square format. Here’s my latest contraption which uses 35mm film to provide square images of 24 x 24mm. Using this size means that you can get up to 50 exposures on a standard roll of 36 exposure film.” [via] Link.
