I'm going to be photographing in a club setting. Imagine a foggy atmosphere, with a lighting nightmare: everything from strobe lights to colored spotlights and everything in between, both bright and dark. The atmosphere is very fast-paced.

I'm looking for tips on lenses, ISO settings, camera settings (I have a Nikon D90 if that helps), since this is such a difficult atmosphere, I want to go in at least having some sort of plan.
