We've spent three evenings in a row now in the studio, working on the lighting. Changing the fill, moving it around, putting all sorts of cards on it, shoot-throughs, scrims, putting gels on the lights, etc. etc. etc. Still ain't working that great. The main problem is that we can never really see what we're getting until we get it home. Hard to see on the laptop screen. As well, because we're processing the shots with HDR tone mapping, the results are erratic as hell.
Gonna have to go back there and work on it with a real monitor.
