I've been trying out delta 3200 lately. I have a fujufilm ga645 that shoots max 1200iso that I'm using a lot right now and I also shot a roll through a ricoh ff-90 35mm at 1200. It's incredibly flat. I'm using D-76 and the times / temps from the massive dev chart app. Does it only give good contrast when pushed to 1600 or beyond? Some tips would be appreciated.
