John, Since I am posting this from home, I hope it will make it to the list.
Great idea! I wanted to do the same for a long time but never actually did it. My idea was to make a collapsible pinhole camera that has a box inside, with sleeves off a changing bag attached through which you can remove the exposed paper or film and put up a fresh sheet. In answering your question: if you use a film box or paper box inside the camera, it should be OK indefinitely. In terms of holding the film or paper in place, how about just a couple of clips? The hardest part is probably how to prevent light from getting in when you stick your arms inside the sleeves. One possibility is to stick your arms inside, put up a sheet of film/paper, work the shutter to expose, put the film/paper away in the box, and THEN take your arms out of the sleeves. A little unwieldy maybe, but beats unnecessarily carrying a big box on a hike, since the whole thing can be made mainly with lightproof clothe, or foldable cardboard. Porter's Camera has blackened aluminum foil just begging to be used on some innovative project like this: maybe you can just bring a roll of it with you, and build a camera right on site as the situation demands. Wow, that's actually not a bad idea... Please let us know what you come up with.
