Part of the studio series I did with Jada back in February...
Post was done in Photoshop: a variation of a technique I read about in Corey Baker's "Down & Dirty Tricks" book.
Strobist info: 2 Elinchrom 500BRX in medium gridded softboxes camera left and right. White lightning X800 in 2x3 softbox directly above camera for fill.
Shot against a mid-tone gray bedsheet.
