Re: UV fading of stained negatives

Sandy and Linus,

I noticed this same effect several years ago with a negative that was
masked and printed probably a couple dozen times. I think I even mentioned
it on the list at the time.

The slight fading of the stain had no apprent effect on the printability
of the negative. It was FP4 processed in PMK.
