I do love some good motion blur. This was shot in the studio, on a white paper backdrop with 2 constant lights, one on either side of the model, one with a cyan gel and one with a magenta gel, both pointed at the backdrop. To freeze the model's face, I used a strobe to the left of camera with a 10 degree grid. I shot with a shutter speed of 1/15, and panned the camera during the exposure.
