Lighting info:
The room was large and fairly dark (even for a wedding reception venue). There were, however, lots of small Christmas lights suspended from the ceiling and a balcony behind me where I placed 2 studio strobes (1 800w & 1 1600w) both blasting into the ceiling (about 40 feet above the dance floor).
The shutter speed was set to 1/5 of a second. I kept the camera moving during the exposure. The flashes froze the dancers' action and the motion of the camera caused the ambient lights to swirl.
