I did a 1600ISO Tri-X in Rodinal 1+100 for 45 minutes stand development yesterday. (actually, the 1600ISO is not accurate, since I used a Zorki1 without meter and in-room illumination...). Looking at the negatives, most shots look OK, but obviously, exposure variance is high.
Only one problem: there's an area of brown color shift in the middle of the negative strip. I had this before, when using exhausted fixer by accident, but I tested my fixer with an undeveloped film lead and it's clear within 1 minute, so my fixer should be OK, right?
My guess is that Tri-X requires extra-long fixing. Or can this be related to the long development time? I can imagine that the negative gets more soaked with developer than when developing for normal development times of ~10 minutes. Can remaining developer agent cause this brown color shift? Should I just fix longer, or is there another remedy?
Groeten,
