According to Henry Wilhelm, Cibachromes have excellent dark storage
capabilities, but their light fading (on display) is only somewhat
better than colour photographic paper.
Much as I like and respect Henry, my Cibachromes don't agree with him. I
have a couple that are matted and framed and were hung on the wall in my
studio for years. The front of the studio is a storefront with big plate
glass windows, and gets direct and indirect sun all day. One print was
hung about two feet from the windows.
I've never tested Ciba's for longevity (haven't actually tested anything
that way).
I've suspected for some time though that Henry's testing methods are
worthwhile for determining how many years a material will stand up to
blindingly bright light and high heat, but not for the conditions we find in
our living room (unless our living room is on Mercury).
