I was processing several (3) rolls of FP4+ in my Jobo CPP2--I mixed Ilfosol-S 1+9 and processed for 5:12 (6.5 min. minus 20%) --I used fresh Stop as well as fresh Ilford Rapid Fixer---All was processed in the correct chemistry order--the end result was the film was clear (no manufacturer info on the edge either--totally clear) for all three rolls---I know the film was exposed. At this point I took the remaining 2 rolls of FP4+ that was taken/exposed in the same film back (A-12 Hassy) and switched to TMax Developer and the same remaining Stop and Fix. The film from the TMax turned out fine ---- What gives on Ilfosol S ? I used a fresh bottle of Ilfosol---Do you think maybe it has the wrong chemical in the bottle?
