During the last few months I noticed Tri-X has changed and now has the dreaded iodine look which some may call purple. I tried fixing for a longer period of time but a longer time in a water bath is the answer. After a clear bath, let the film stand for about 7 min in a water rinse with 2 or 3 changes of water. Then rinse for 5 min under running water. Experiment on the film leader to check fix and stain clear times. The film will still have a slight iodine cast which I find pychologically unpleasent compared to the gray cast of AGFA film. This stain does bleed into your fix.(posted 8969 days ago)
