OK so it is possible I overestimated the amount of time we would have to do these projects. Once a week was optimistic but I can promise we will try to do these as often as we can.
For now, I wanted to call to your attention an organization I sometimes volunteer with, it is called Operation Photo Rescue. I started working with them when I was in school and they were looking for volunteers to help restore photos for victims of hurricane Katrina.
Restoring images are a great way to get comfortable with using your cloning tool in Photoshop, not to mention color correction. The best resource I have found for restorations is Photoshop Restoration and Retouching by Katrin Eismann. Chapter 6 in that book is dedicated to “Damage Control and Repair.” I have used that chapter so much that the book simply opens to it now when I drop it on my desk. The main tools I use are the Clone Stamp, Quick Mask, the Warp option of the Transform tool and the lens correction filter. If you know how to use those tools you can do your own restorations for your family or friends or volunteer to keep those skills sharp! I would also recommend checking out OPR’s site as they also have a great archive of tutorials from other volunteers.
Below is an example of one of the restorations I did for a family friend. The best tip I picked up from this one was selecting the color channel with the fewest imperfections, in this case it was red, and then dumping the rest of the color channels when I set the image mode to grayscale. This gave me a much easier jumping off point than the before shows.
