I've been using Pyrocat HD for my 35mm TX negatives for most of my work in the year, year and a half. I've pulled my best results from TX using this developer. The liberally exposed, full range, negatives I like have given me prints I am very happy with. This is a great combination for 35mm, period. What is giving me cause for doubt, however, is that I am not perfect. I do not always estimate my exposure correctly. I shoot in difficult lighting. Ocassionally I even "push" my negatives. Printing less than ideal negatives sometimes requires making prints with accentuated grain. Printing at high contrast grades from weak negaives for example. What I'm driving at here is that although the perfect print from the perfect Pyrocat/TX negative has a very minimal, "masked," grain sructure, that grain, when unmasked is, well, clumpy, confused, unattractive. To be blunt. I can say the same thing for Pyrocat HD and HP5. I thought I would share my experience with you and inquire as to your overall experience with Pyrocat HD and 35mm films. Thanks!
