Thanks for the responses. I ran the films today in straight X-Tol, before I saw John Hicks'reply. The results (films all exposed at EI 3200): Ilford Delta 3200, developed for 7.5 mins @68 degrees was BEAUTIFUL! The TMZ, developed for 11 mins looked underdeveloped - thin and flat - but printed okay. The Neopan 1600, also developed for 7.5 mins @68 degrees was contrasty, the highlights very dense and shadow detail lacking. Less developing would probably have brought the highlights down. The lack of shadow detail might have been a result of differences in stage lighting from when the other films were exposed.(posted 9134 days ago)But I am so pleased with the Ildord film that I will stick with it. The X-Tol seems to be every bit as good as everyone says. I ran some portaits on Plus-X in X-Tol and they're very nice. But I don't like the powedr, especially part A! It was difficult to desolve.
I used X-Tol straight to avoid long developing times. I also figured I would get maximum "fine grain" effect due to highest sodium sulfite concentration. But I need to experiment with different dilutions.
Thanks again to all who responded.
