Technical crap in case it matters to you:
Two Nikon Speedlights, one through an umbrella from camera right and above, one from behind the subject through a small plastic diffuser. Both speedlights were triggered via Nikon's wireless infrared "CLS" control system. Edited in the GIMP and quickly resized in Picasa. Nikon D300s and Nikkor 85mm f1.8, @ 1/200th, iso200, f2.8.
