I was wondering...most of my prints are 8x10 or smaller. Shooting 120 film, will I notice a difference in clarity or grain, using 100 (or 125) vs. 400 speed film? I've typically bought 100 speed film out of habit from my 35mm days, but the thought occured to me that with the prints I make I might be a bit overkill. Part of the reason I ask, is that I'm thinking of playing with my TLR Ricohmatic 225 w/ out a tripod and the 400 speed film might be more forgiving. Thanks all.
