These two questions may be no-brainers to most here, but I'd appreciate
some help:
1. What is the surface area of slide film, 135 - 36? (Or the surface
area of 120 or 220 - I don't even know what these numbers stand for.)
2. Where can I get exposure times for pinhole cameras? (Is there a way
to determine the ASA, or do I just use that of the roll I am loading?)
Thanks.
