This is a plan for a pinhole camera that is made from layers of plywood (or anything layerable, really ;). It has a round image plane, the idea is to get a broad field of view.It's not yet tested, so I don't have any idea what kind of pictures will come out of it, but I'm building two right now.update: Attached a picture made with the cam. It works. :)The Idea is to glue the layers of wood on top of each other to get the case. The round containers at the sides are made for two 35mm film canisters, so the film can be spooled from one into the other.I've included an picture that might make the assembly a little clearer.
