How did you do that?: While photographing Pau Gasol of the NBA in the Electronic Arts MOCAP studio I used a slow rear curtain synced flash and used an effect called zoom blur to create this image.

Having the subject hold still and the camera set-up on a tripod I used a slow shutter speed (1/8th) of a second and zoomed my lens out causing the red MOCAP lights to streak with my strobe lights set to fire just before the camera shutter closes.
