How can I stop the yellowing of old photos?
Q. Dear Donia,
A. Dear Phyllis,
I am guessing the photos that you have are color. The yellowing is not an uncommon type of deterioration as the different dyes in the photograph start to fade. Unfortunately, there is nothing that can be done except to keep the photographs in the dark and as cool as possible. You may want to get the most important photographs scanned before the photos get too yellow.
Sorry I cannot give you better news.
