[Canon 5D, EF 70-200 f/2.8 L IS @ 110 mm, ISO 100, 1/160 sec., f/2.8]
Two speedlites and one 5-in-1 disc = simple. The lighting and the crop are Peter Hurley inspired. Here is a very nice, free, little internet tutorial 10 Ways to Shoot Stunning Portraits With Only One Light.
NOTE: A softbox (Photofelx LightDome Q39 with a 580ex II inside) is shown. Spill on the background would be okay here and a shoot-through white umbrella would have made this even more simple. The light for the 5-in-1 disc (hanging from my DIY Justin-Clamp) used as a background was a 430 EX.
