I use a very quick two step process but it works great for my use...
1. I use TLR edge mask action (available free on
http://www.thelightsrightstudio.com/home.html) to create a mak for the edges. This preserves the surfaces from getting sharpened (like clouds, cheeks etc. which do not need sharpening)
2. Run USM on the layer with the edge mask on...this only sharpens the edges leaving out the surfaces...
Sometimes, I paint on the mask as well if I see areas that get selected as edges when they are surfaces...
Anyone else use something similar?
Let me know if you have any questions...Have fun...
