I am setting up the Jobo ATL1500 next week to process Tri-X (35,120,4x5); I would be interested getting a sense of your thoughts and experiences. I would like to use Microdol-X 1:3 for the 35mm Tri-X(E.I.260); Microdol-X stock solution for the 120 (E.I.400); haven't made up my mind for the 4x5 but in the past I have used HC-110 (B). The new times for the HC110 are so short, however, that I worry about uneven development. Just to make it more interesting, I'm thinking of also processing HIE on the Jobo with Rodinal 1:13 I have seen some posts that allude to problems when it comes to diluted developers, but nothing very specific. What do you think?!?
