Greetings,(posted 8406 days ago)My experience with Pyro developers is quite limited, but I don't think your results have anything to do with the developer. I have used all of the film you named and Pan F+ behaves much differently than HP-5 or FP-4 in terms of antihalation clearing. In "standard" developers, both HP-5 & FP-4 will produce a nice clear film base in Kodak Rapid Fixer, whereas Pan F will have a pinkish coloration. This is usually attributed to insufficient fixing/washing. You tried refixing, but perhaps were unsuccessful due to the Pyro staining - sorry, but I don't know enough about the side effects of the Pyro developer. That pink tinge is characteristic of T-grain films and Pan-F that have been insufficiently fixed and/or washed. You may want to stick a piece of unused film in TF-4 and time how long it takes to clear.
