I have recently tried XTOL on two test rolls, and have had very disappointing results. First off was a roll of Tmax 100 shot at 100, developed in XTOL 1+1 for 14 minutes. Negatives are thin, as are the numbers by the sprocket holes. Same with ilford PAN 100, developed for 13 minutes. I used times from the massive dev chart and threw on a couple of minutes for each, so i could start working with my process from there. But the results are poor, and I am not sure if i just have a bad batch or something else is up! Any advice would be appreciated, i have never had such problems developing B/W before these are the worst two rolls i have ever processed! Good thing they were not critical ones. Or have i experienced the dreaded XTOL failure? I mixed it a week ago exactly, in a 5L PET container with butane gas to protect it, as i do with all my B/W and colour chemicals. I have had no problems with home-made ascorbate developers, or am i missing something? Advice would be appreciated!
