My own >"controlled" tests suggest that air exposure is of very great importance. I'm kind of beginning to wish this discussion didn't remind me of the American Cancer Society and the American Heart Association debating over which disease is the most important killer. I find it hard to see this as an either-or thing. There is a huge weight of evidence that shows that increased exposure to light will cause prints to fade faster, and almost everyone has seen practical examples of it--which would appear in no way to negate the possibility that air exposure can have a significant effect even in the absence of strong light levels. (Not my air, mind you--I live in the middle of nowhere in Idaho. But the rest of you may have to worry.... (:>) Gary Hunt <glh@srv.net> - Please turn off HTML mail features.
