Lighting:
Shot thru a rinflash (ABR800) with a moon unit softbox straight on.
The camera was set a F11 @ 1/200 sec at 100 ISO
Processing:
1) Levels at red, green and blue to find whites and blacks at each channel
2) Curves to define white and black
3) selective coloring. I darkened the magentas and reds only
4) removed imprefections and smoothed skin
5) did highlights/shadows on the masked hair
6) Dodged the highlights on her face and hair
7) burned the wall to add character.
8) sharpened the eyes, lips and wall
