I've compared 35mm Delta 400 using DD-X and ID-ll. I've found DD-X 1:4 works well with this film but I prefer ID-11 straight best, ID-11 1:1 second. For my taste, stock ID-11 just seemed to give a better grain pattern on people shots. DD-X, of course, wins the convenience- of-use factor.(posted 8272 days ago)
