Ok, I believe this is close to the technique that Dave Hill and Jill Greenberg use on their photos with PhotoShop. The tutorial takes a few minutes to complete. You must start with a photo that has wrap around lighting and obvious highlights.
Make sure the levels and color are fixed on the original before you start.
Duplicate the layer on the LAYER pallette
Go to FILTER – OTHER – HIGH PASS type 4.0 for RADIUS
on the LAYERS pallette choose vivid light for the blending mode
Now flatten the image.
