This is strange, because purple negatives usually come from the newer technology films like T-Max and Delta. How long are you fixing? Kodak Fixer requires as much as 10 minutes, and Kodak Rapid Fix needs up to 5 minutes. I also think Hypo Clearing Agent helps (1= minutes) and a lot of the color will wash out in at least a 5 minute wash at 68 degrees where the water changes twice a minute.(posted 8999 days ago)
