Wrap lighting is where you have 3 or more light sources surrounding the subject (usually from a higher angle) to rim the edges and add specular highlights wherever possible. I want more flashguns so I can get even more highlights, but for the moment Im happy with 3.
The post processing is a mixture of selective high pass sharpening, and a small amount of dodging around the front (I underexposed the front light) followed by a highradius unsharp mask layer applying the "lighter colour" blend mode.
I've been toying it with a few months, and the post processing doesnt work whatsoever if the lighting isnt right! so Its a 70% capture 30% photoshop kind of technique.
As for the armpit comment, no I dont. When i was 13 hair started growing there, then it got bored. Dont ask me why..
