Paul Ernest Debevec is a researcher in computer graphics at the University of Southern California's Institute for Creative Technologies. He is best known for his work in finding, capturing and synthesizing the bidirectional scattering distribution function utilizing the light stages his research team constructed to find and capture the reflectance field over the human face, high-dynamic-range imaging and image-based modeling and rendering. Debevec received his undergraduate degree in mathematics and engineering from the University of Michigan, and a Ph.D. in computer science from University of California, Berkeley in 1996; his thesis research was in photogrammetry, or the recovery of the 3D shape of an object from a collection of still photographs taken from various angles. In 1997 he and a team of students produced The Campanile Movie (1997), a virtual flyby of UC Berkeley's Campanile tower. Debevec's more recent research has included methods for recording real-world illumination for
