Well, the fixer was made up fresh from the bottle, but the bottle had been opne for several weeks, so maybe it was a little old. I did notice that the fixer came out a little purple (and so did the film - TMZ), although it appeared to clear up by the time I did the second film (Delta 3200 - which did not come out stained). The antihalation dye idea along with not perfect fixing make sense. thanks.(posted 8354 days ago)
