In 1950

...my father was born, on November 29th, almost 61 years ago.

My grandmother asked me today if I could print those photos in a larger size (they are 5,5x6 cm) and maybe frame them for her.  So now I've scanned the photos and plan to remove the scratches and fix a few blemishes in Photoshop.  Might take a few hours but I think it'll be worth it in the end.

Any suggestions for repairing old photographs in Photoshop? Tips and tricks? :o)
