I have been doing zone system testing with HP-5 in Xtol 1:1 in a Jobo processor. My time for normal development with zone VIII at 1.30 density is 12 min. at 70 degrees. This time is 50% greater than the time published by Kodak, which makes me wonder if I have done something wrong. Has anyone else had a similar experien ce with HP-5, Xtol, and Jobo processing?
