Can yall remove the alterations from the original?
I scan the original to my computer and retouch the scanned image, then I retire the original. Once I complete retouching of the scanned image, I print it on photo paper. I've done that to my grandmothers wedding photo from 1920 and a picture of my granfather and his uncles taken in 1917. Actually, that image was sent to me via e-mail so I don't have the original.
They both turned out very well.
