The Light Stages and Their Applications to Photoreal Digital Actors
Paul E. Debevec · 2012
5 uses high-speed photography to record an actor’s reflectance with time-multiplexed illumination; Light Stage 6, at 8m in diameter, allows performance relighting for the whole human body. The Light Stage systems built at UC Berkeley and USC ICT have enabled a variety of facial scanning and reflectance measurement techniques that have been explored in several research papers and used in various commercial applications. This short paper presents the evolutionary history of the Light Stage Systems and some of the techniques and applications they have enabled.
