I think I need to rephrase my question. I just realized: the EV
doesn't change when you change the ISO. Duh. But, the question
remains: when you expose 320 or 400 film, do you use the same
exposure that you would use for 100 speed film? That is, light
sufficient to get an EV of 4, and 2/5 of a second? Or would you use
a shorter exposure, or what?
