Re: [Utah-astronomy] Galileo, time

I think negatives tend to last well if properly processed and then not mishandled. That's a different task than preserving prints. Anyone have ideas about that? Thanks, Joe

Joe, I was a color-lab tech and printer in a former life. The best thing you can do for your negs is to store them in acid-free sleeves, in darkness and very dry air. They should last for decades. Some color-shift will occur, but a good printer worth his/her salt can get a reasonably-neutral print with a little care and proper filtration. If you wanted to go whole-hog, you could further store them in a neutral gas such as helium. C.
