Another recent 100 year old photo restoration I did for a recent new customer. This was from a time when the images were printed on a type of paper with the rough consistency of cardboard, and were retouched with charcoal for shadows and a bit of paint to bring out the highlights. This was approximately 11X14 and had to be extremely carefully removed from the frame and mounting as the entire thing was falling apart, the wooden frame was crumbling into sawdust and the print was in terrible shape. About three hours later I had it to pretty much what I could determine the original would have looked like. Afterward I had to rebuild much of the frame before returning it to the client, who was absolutely thrilled (the subject was her mother when she was a child) and now I'm shooting her daughter's wedding in a few months!
Note: No extra painting of details or dodging and burning was needed, although it took two scans and stitching software to get it to look right.
