I'm sure I've read about this somewhere, probably here. But search as I might I can't turn the information.
What I'm looking for are the actual measured sizes for 8x10, 5x7, and 4x5 films. Also the actual measured image sizes. I know that 4x5 isn't really 4x5, it's something smaller like 1/16 or 3/32 of an inch smaller. The image size is smaller yet, like 1/4 inch smaller, so 3.75 x 4.75 inches. Yes? But what are the numbers for the larger sizes?
I'm thinking there's an ISO standard for film sizes that lists sizes, tolerances, all the rest. There is perhaps one for film holders as well. If anyone has a pointer for me, I would appreciate it.
