I'm always looking for ways to show off. Now if I can find a sculptor.
Note: I brazenly snagged the Mt. Rushmore pic from somewhere on the web. Apologies to the person whose copyright I've violated. Trust me, I won't be selling this thing.
PS - Extract face image from original file, desaturate, and add to the base image. Back off layer opacity and other twiddles to match the basic rock color and texture. Clone (e.g., from Lincoln's beard) various areas. Dodging, burning, smudging, and other futzing to meld head into the rock. Putz for entirely too much time tweaking color, contrast, etc., etc. (Obviously, I need to get a life.)
