This snapshot from around 1976 was so very faded and scratched, really in bad shape. I duplicated the photo, and used the multiply blend mode with about 60% opacity to get a lot of the vibrance back. I used several different adjustment layers for exposure, levels and something else that I don't recall...3 adjustment layers. I then used another duplicate layer for high pass sharpening. After that was flattened down I used a small amount of the surface blur filter to decrease the texture of the photo. Then another duplication and another high pass filter sharpening (duplicate photo, high pass filter, then soft light blend mode). After that it was just clean up a few spots with the healing brush tool and final crop. Took a lot longer to get the photo half-way decent (it was a lousy snapshot to begin with, but great memories) than it did to do the layout.
I used Brandy's Cottage Christmas collection.
