To do this, all that is needed is a Polaroid Land camera, some small screwdrivers, and a small sheet of thin metal. These cameras can be found on eBay, or better yet, at yard sales. It will be made into a pinhole camera with several pinholes that can be switched into place, for use in various light conditions etc.
Hmm. I just managed to load film into this beast (not as complicated as it looks but fiddly enough, to be sure). Now I find this. <sigh>
I guess I can work through the 10 sheets of film and see how it works (at $2/sheet, yuck!).
