I just came from the darkroom where I found that all my supra ja ultra endura boxes may have gone bad. They developed very dirty warm white. When I put an unexposed paper straight into the bilx, I got nice clean whites. But processing it through developer makes the whites go brown/gray. Is this typical for outdated paper?
As this was true for 3 different boxes, I tried mixing fresh chemistry from different brand, omitted the stop bath, chased for light leaks in the darkroom and everything else I could imagine. The papers are around 1.5 years old and have been always refridgerated except the past two months when they have been in cool ambient temperature.
How long do your papers typically last?
