Have you ever gotten confused when using different cameras? I am one of those multi-functional (haha) guys, must have three of everything. Anyway, this week while out shooting on three different ocassions, I used all three of my medium format cameras (Mamiya RB67, M645 1000s and the Bronica ETRSI). Switching between the Mamiya 645 to the Bronny was okay,but when using the RB 67, I forgot to advance the film on about 6 shots (dumb) so now I probably have that multi exposure thing going on. Since going med format, I take more time to compose my shots, now I must concentrate/spend more time on advancing the film!
