For genealogists who have old family photographs, a new article in the MakeUseOf web site should be required reading. The article by Harry Guinness says:
“Everyone has old family photos lying around. If they’ve been sitting in a box for a few decades, though, they’ll be discolored, faded, and probably scratched or bent. With Photoshop, you can make them look as good as new.
“For this article, I’m going to assume you already have a basic understanding of Photoshop’s major tools and how to use them. I’m going to focus on strategies rather than the minutiae of the spot healing tool.”
