My friend, Laura, asked me to try to restore this photo of hers. She had found it, and it is one of the few photos with her great-grandmother in it. It was pretty badly damaged. I told her I could not promise anything, but I tried to do some retouching to restore as much as I could.
This was done using the premium version of Picnik on my laptop. It took about two hours. I was unable to fix the boy's mouth (by the father). However, overall, I am pretty pleased with the results. AND, more importantly, Laura is pleased.
