If it’s not digital, you’ll have to find a scanner. If you do, make sure you have a dry cloth that will get rid of any dust on the pic (and the scanner bed), scan to a file with a non-compressed format, and get the highest resolution you can; then scan another file at about half that resolution, in case you have trouble editing the really big one later.
Thank you for that information. I’d like to set up a scanner someday and try that with old photos and slides. Any advice on a basic, easy (intuitive) photo editor?
