One thousand lights at 200mph

The opening race of Cars was designed to look like the racetrack in Bristol, Tennessee. This led to some interesting challenges in that we needed to capture that look across a very large set with many light sources from a wide variety of camera angles. However, since there are so many shots in this sequence, there were two parallel concerns that went along with the aesthetics of the lighting setup: shot lighting efficiency and rendering optimization when dealing with the massive numbers of lights, shadows and reflections.
