I've been doing my own E-6 for a while, and have never had this problem in such an extreme form: Old RVP50 - O.K.; New RVP100 done in the same batches - loss of shadow detail, and much more contrast! At first I thought maybe too much agitation for the newer emulsion, but haven't been able to find any answers from anywhere. I'm using Jobo tanks on the CPP2 processor, and the Tetenal 4-step. Increased 1st developer 16 %. Any help would be appreciated.
