There is one major difference between #digital #photography and #film #camera photography. It's something I've been trying to adjust my brain to... It makes me feel like I am learning photography all over.
Exposure compensation will be something to wrap your head around too. I learned on a DSLR, but with books from the library from when there was only film photography. Film speed, shutter, and aperture pretty well directly transfer, but there is no such thing as an exposure compensation control for film cameras.
Most of the time I pick an ISO/ASA for the day and just leave it, though I am getting more comfortable with changing it as I see fit.
