This is the original poster again... Thanks for the great responses. The problem has been solved by re-fixing the negatives. They are now clear. In the future I plan to fix with Arista 1:9 for 5 minutes with continuous agitation for at least the first minute or two. I'm surprised the Arista instructions claim fixing in just 1-2 minutes. Thanks again for all your help.(posted 8157 days ago)
