I'm thinking about making one or more ultra large format homemade cameras. I'm talking about a foamboard (or something) box that I can tape or glue (or something) together and that I preload with one sheet of something such as a 16x16 sheet of film or thereabouts. Thinking of zoneplate or pinhole apertures principally but maybe some lenses too -- make the box dimensions set up exposure at hyperfocal distance etc. Set the camera at a desirable location and expose. Very big very cheap one-shot point-and-shoot. Anybody aware of a website or book or something that has some sample plans, suggested materials for such a thing? I know this isn't rocket science but I'd be interested in what others have done. -jb
