I recently got a Contax 645 and have been shooting Delta 400 as my main b&w film to get some more speed. My other camera is a RB67 in which I shoot almost exclusively Delta 100.(posted 8132 days ago)The rolls of Delta 400 I've developed thus far have very noticable grain on 8x10 enlargements! The negatives are sharp and snappy, but grainy, especially in the out of focus areas! I've never had grain problems with Delta 100. I have a big backlog of undeveloped Delta 400 and I'd like to figure out this problem. I'm rating at ISO 400 and developing in Ilfosol-S at 1+9 for 10min at 20C. I'm printing with a Omega B-7 condenser on Ilford Multigrade IV RC pearl developed in Ilford Paper Developer at 1+9.
Has anyone else had this problem? Suggestions for fixing it? I'd like to stick with Ilfosol as I get nice results with 100 Delta. If there is another developer suggestion I prefer one shot liquids. Thanks!
