Developed some this weekend - had two sheets of film (both Efke PL100, 5x7). Exposure was the same for both films 1 sec @f/45 (see rail image here - this print is from the Rodinal negative). 1st negative was processed in Pyrocat-HD 2+2+100, (or 10ml+10ml+500ml), negatvie was place in a Beseler 8x10 drum, pre-soak of 2 min in H20, the developer for 12 minutes, dump, water stop for 1 min., then fix for 5 min., rinse, and remove negative from the drum. The shadow areas along the rail, bottom center of the image, were just visible. Rest of the negative looked very good, except on the emulsion side, there was a slight amount of dichoric fog. Now, am using a Unicolor roller - going back and forth, is the fog coming from oxidation of the developer because of too much movement? The time does not seem out of line. The 2nd negative was processed in Rodinal 1+50 for 12 min also, same process with pre-soak, develop, H2O stop, and fix. That negative is the one placed in the gallery. The shadows have good detail and look pretty much like I had envisioned. When the scene was metered, place the shadows in Zone III and high lites were placed on zone VII..so the first impression I have is that I did not give the Pyrocat enough development time - which is OK, can understand that, but past experience has shown me the more time I give it the worse the dichroic fog will be - any suggestions. Really do like the look of the P-cat negatives, just wished I could figure out how to avoid the fog... As always thanks for your input.
