This was a fun project.
A neighbor recently asked whether I could restore and copy a class photo made more than 70 years ago. The photo shows a Greek school class in Washington Heights, NY.
The photo was apparently in its original frame, sealed with tape in the back, and yellowed from age. The challenge was to copy it in its frame but without glare from the glass covering.
A polarizing filter helped me make a copy of the photo without any glare, and it just needed some spot retouching in Photoshop to look great. It will be printed on a beautiful fine art paper with just a little warm toning. Here is a very small version of the result (the slight glare on the back wall is in the original):
