Taken with a D3s, 24-70mm lens, and 4 SB-900s.
Shutter is 1/250th
So the light you see is all flash, there is no ambient light.
A group is an umbrella set to +2.0
B group is my rim light on a C-Stand hanging over to camera right in an LTP. I want to say that it was at +1.3
C Group is my fill light. It was an a lastolite mini softbox.
Final flash is the commander.
