Having a studio setup right there in the office provides a lot of good opportunities for goofy photos of co-workers, especially when testing lighting setups. These shots usually don't see the light of day, but for a goofy shot, I really liked the lighting on this one. Setup is two gridded 24" soft boxes, one just above to camera left as the main and a second slightly behind the subject as a rim light. There's a bounce card directly in front of and below camera to throw a little fill, and a blue-gelled backdrop light behind the subject.
The main box is in close, which provides the good light falloff allowing the arms and lower body to go dark.
