Strobist: Nikon D3, 17-35mm 2.8. 1/200th at F/9, ISO 200. For the main light, I used an Elinchrom Ranger AS with an A head shooting through a varistar brolly box to camera right. I also used a couple of gridded Q-flashes (one to light the foreground slightly and one out side of the frame to camera left as a rim).
