I've been crawling around the threads here and getting increasingly curious about pinhole cameras. Recently a link was posted to the work of Jeff Korte, whose work I very much liked. One of his galleries is of images made with multiple-pinhole cameras. Probably not everybody's cup of tea, but I found the whole idea to be very very intriguing. Any ideas how this is done? I think I can picture the obvious bits (custom made camera, an array of aperture holes selectively opened and closed), but I'm wondering about things like - would each exposure be timed as you would a "normal" exposure in those conditions, or for shorter periods (as when you compensate for purposeful double-exposures)? In such a camera, is the distance from aperture to film plane dramatically shorter, or longer, and by how much? I'm having trouble picturing how one controls the area of film (or paper) that gets exposure from each individual pinhole.
