Going through my archives I found about ten rolls of 35mm from a year ago that have a yellowish cast to them. This was early on in my film processing career when I didn't understand too much about fixer life and I think I may have fixed them using exhausted fixer. The negatives aren't cloudy but just have a yellowish cast to them, quite different than the usual grey or greyish-purple cast my negatives usually have.
I was thinking about carefully loading them onto reels and re-fixing and re-washing them. Any tips? Should I presoak first? Do you think it's necessary?
