The subject is out of the picture to the middle left. A young assistant held the sunshade over their head to shade the subject. An older assistant held a 550EX in front of the reflector umbrella. I wonder if the light from the sun was more than the flash. The photographer's equipment seemed to be: $1700 Canon EOS-1v, $1700 Canon 70-200mm f/2.8 USM IS lens with hood, Gitzo monopod, camera-mounted 550EX master flash with flipdown diffuser, hand-held 550EX slave flash, white reflector umbrella, small light stand with flash bracket, cloth-on-frame square sun shade, There may have been a light meter but I didn't notice it being used
