Now, I've pushed Portra 400 before, never with push processing though. So I shot a roll at 1600, no ev adjustment, just Aperture priority. Then processed for 3:45 (pushed one stop) and now the results, grainy, very horrible. I have another roll ready to process done on the same day. Should I try to push it more or less, kinda of at a loss as to why this is not working for me.
