1. How do photo booths work? (you know, the little booths where you pay ~ $1 and get a strip of 4 photos). Are they polaroid, contacts or what. 2. I would like to get a medium format camera with a ground glass viewer, (perhaps like the Pentax 6X7), which also can take 6X6 negatives. I have heard that some cameras have this capability through separate backs. It seems to me that if a camera already has the capability to take 6X7 negatives, to allow it to take 6X6 would be simple. Two things would be necessary: a way to advance the film 6/7ths as far as for 6X7, and a way to extend the sides of the film frame to allow only a 6X6 area of the negative to be exposed. My question is, has this method been engineered into any cameras, and if not, why not? Is it prctical to modify a camera to do this? Anthony Albert ..!ucbvax!kim!albert albert@ucbkim.berkeley.edu
