Todd, to do this kind of thing correctly you need lights. If I were shooting this room I'd want to have at least two speedlights in the back of the room with (small) softboxes over their dome diffusers, hidden behind whatever's usable to hide them and pointed at an upward angle at the back wall and the ceiling. I shoot mainly with Nikon cameras. In this room I'd be able to use the SU-800 to control the lights remotely since there'd be plenty of reflection from the SU-800's IR flash. But if things were more spread out I'd switch to Phottix Odin radio control equipment. I'd suggest simply bouncing a flash off the ceiling as I've done in this shot, but you'd probably get some pretty bad, unexplainable shadows that way. In any case, you can't do it right without lights.
