My friend John subject-guinea-pigging for me to test out some lighting setups.
Strobist: 1 580EXII through white umbrella camera right. Bare 580EXII behind and above the subject camera left. Strobes were at about 1/4-1/8 power. Fired with PW Plus II's.
Colour grading and some localized adjustments in Lightroom 2.0.
