One of the programs I am using for this project is Photoshop CS2. Besides resizing and eliminating blemishes(scratches, water spots, etc.), Photoshop can help fix color that has faded.
This photo of James Hughes at A2 (provided by James' daughter) had turned yellow. But this can be easily fixed.
Here is the BEFORE version of the original photo:
This is the AFTER photo:
Pretty amazing results!
