I am setting up a PhotoTherm processer to do cut film. I will be shooting FP4. The instructions are geared to TMax developer and show a development time of 3:30 minutes @ 75 F. I plan on using PyrocatHD in the Glycol base. I checked with PhotoTherm's tech supoort and there is no ploblem with this developer. I questioned them about the seeming low development time for FP4, which is about half of the Ilford recommended time. The gentlemen indicated that it was that the B&W processing is done at 75 F. In the instructions for the PyroCatHD it shows for rotory processing a base development time of 7:15 minutes @ 75 F. I am looking for a correct starting point to develop the FP4. Has any one got experience or insight they can share?
