Re: Scratch/Crease Problem
Your post made me wonder about the age of the photo also. I asked the owner if he knew anyone in it and it turns out that the little girl on the front row in the center was born in 1924. I am revising my estimate of its age to 78 to 81 years. Thanks for calling attention to it.
Cupcake, I'm trying your idea now. It seems easier to me than making an accurate selection.
Unimatrix001, I will experiment with your idea tonight and report back.
Thanks to all who posted on this problem. You've all reinforced the beauty of Photoshop in that it provides multiple ways to solve a problem.
