Desaturating to fix an older photo

I need to remember this layer effect more often.  See the difference between the full color and the desaturated one?  (photos from 1980's)   Desaturating got rid of the awful sunglare  in this shot.  To make the layout, I copied the square part with the kids and then put a white layer in between and used the opacity slider to make the base look like vellum.  A tip I got online somewhere.  Sunshine is a word art I downloaded from another scrapper's website.  Gotta love the generous freebies out there.
