I passed by a photoshoot yesterday, and paused to check out the gear and technique. It was a Canon shooter, taking staged shots for a corporate brochure, and he had a mother/daughter posed in front of a flowerbox. His strobe was on a stand behind him, shooting into a white 45" umbrella, and providing fill. It was a monolight, and he had it cabled to what looked like a minature car battery to power it. He has a PW transmitter in the hotshoe of his camera, and a receiver hanging off the strobe. All I could think was, thank goodness I'm a Nikon shooter. I can do the same thing controlling an sb800 with an su800 or with my camera's internal flash. No need for external batteries, cables, transmitters, receivers and such. Nikon sure made it easy for us :biggrin:.
