If you browse reddit, you may have noticed that when someone posts a very old picture of a relative, someone always restores and colorizes it as a gift to the submitter. A lot of these amazing photo restorations are done by Swedish artist Sanna Dullaway. She has also colorized many historic photographs.
Dullaway recently started her own business in restoring old photographs, but the website is still under construction. But there are other places to see her work. Link to reddit album. Link to Dullaway's Flickr stream. -Thanks, özi!
