I have had fun (and I think success) in retouching some of our old family photographs to get rid of spots, lines, damage, etc by using photoshop. I know that places like walgreens offer a similar service and I would guess they do a similar process but what I don't know how to do is how do they take an original black/white photo and then change it to a color pic? My real question is does photoshop do is, if so, how? Is there another easy program or do they just painstakingly replace colors as they go along?
Enquiring minds and all that.
