Hi there, I am currently working on a long term portraits project (around 50 peoples with thre shots per guy) and I need to choose the best developer I can find. I use mainly HP Delta 400 at EI200 or Kodak Tri-X Pan at EI200 too. For the Delta I am currently running a series of tests with Ilfosol S, Ilfotec DD-X, Ultrafin Plus and Ultrafin SF. Has anybody performed such a test and would be willing to share their info? Many thanks(posted 8267 days ago)
