Here is a question for you negative souping masters. I was reading somewhere that someone only uses ISO 100 film (I think it was Delta 100). They use no other film. When they need ISO 400, they just take the ISO 100 and EI 400 with it.(posted 8522 days ago)Would it be better to expose ISO 400 or EI 400 (with ISO 100)? I know the trade-offs for pushing would be less shadow detail, more grain and more contrast. Which would look better in regards to finer grain and tonality?
I'm sure I could try it for myself but if someone has already done the experiement, inquiring minds would like to know! Thanks!
