I use notepads to record exposure info, dates and locations. I've tried forms but you need something to push against when writing which I never have. The notepads have a cardboard backing which is enough. I transfer that into a MS-Access DB which also records film development and enlargement info. This is designed for roll films and I need to add something to suit sheet film. I print a report (usually 1 page) and stick that with the contact sheet in a clear sleeve which goes in the neg folder in front of the negs.
