I'm pretty enthusiastic on Pan F. I think it was Rodinol that was used on the first roll & was not impressed at all. It was Eric Rose's posts that let me know the dilution/time/temp for Pyrocat-M - on Massive Dev chart - worked just great w/ Pyro-HD. I shoot at ei25 & dev for normal box speed. Its a regular dilution/agitation cycle, not semi-stand. http://www.digitaltruth.com/devchart.php?Film=Ilford+Pan+F&Developer=Pyrocat&mdc=Search&TempUnits=F
