- Photos NOT OK to edit
Long time since I've been here - must visit more often. I agree that it is reasonable for the instructor to insist on a fixed ISO when teaching studio photography but I just wonder why 100 and not 200. I've yet to use a digital camera that produces better image quality at 100 than at 200; after all their sensors do not behave like film and 200 seems to be the "natural speed" of most sensors. With modern studio lights offering a minimum power setting of at least 1/32nd, I can't see that anyone would often need 100 ISO even to achive minimum DOF with very fast lenses wide open. As you would guess, I don't use ISO 100 and I do a lot of studio work under flash.
