I have been going through youtube videos for photo restoration and its amazing what can be done, unfortunately i realized early on I don't know a lot about the basics of photo editing. It seems I need to pick a software tool, learn the basic then get into retouching the old family photos. But where to start is daunting. I have access to GIMP and pixelmator, but not sure this will be the best tools for going through ton of old family photos I need to clean up. the expense is a an issues, but am i wasting my time by just no starting with photoshop? Is there any standard tools or tutorials for learning how to restore old photos? If GIMP or Pixelmator are good options, are there any good tutorials for them?
