Finally got around to starting my own testing using Ilford HP5 Plus, D76 and my Jobo. Using Steve Simmons method I shot the film at different speeds and found my minimum time for max black using Ilford glossy fibre paper using a grade 2 filter. At F:16 it was 22 secs.
Tonight I will print the negs to find my EI, and tomorrow, using that EI, will shoot five more negatives to find my ideal developing time.
Anyway, I have a lot of different papers available to me (I get good deals from local students who just graduated) but I think I read this testing is only good for the film / developer/paper I am using. If I want to print to Ilford RC glossy, do I need to repeat the process all over again?
