Simple light from 100w desk lamp. Sorry I look like such a sourpuss -- but, I guess I'm just an old sourpuss.
SP - Crop. Levels adjustment (to overcome yellow tint from the lights). Small USM adjustment. Soften focus with a duplicate layer w/Gaussian blur (~10), normal blend, ~35% opacity. Eyes erased on blurred layer so sharp focus shows. Extract out background and fill with solid black. Color version saved. Convert to greyscale. Layer adjustment to contrast/brightness. B&W version saved. Convert to duotone. Use dark Pantone blue and black as duotone colors. (Intention was to keep photo essentially B&W but a bit softer than black on black would give. Tweaked the blue curve.
Using duotone (vs colorizing, etc.) was Jeanne's suggestion. Also, this is the first time I've tried the GB to soften focus -- also Jeanne's suggestion. (She's a treasure on many levels, ain't she? Don't tell her I said so, though; she's likely to get a big head of red hair.)
