I have tons of old photographs that I will be converting to digital (photographing) and most of them have curves (are not comletely flat).
I also have this piece of glass from picture frame, but I don't want to use it because, reasons, fingerprints, reflections, etc...
Is there any other way to flatten those photos? I was thinking clear duc tape, but that would be too messy and time consuming for nearly 500 pictures..
What do you think?
