e present a near-instant method for acquiring facial geometry and reflectance using a set of commodity DSLR cameras and
flashes. Our setup consists of twenty-four cameras and six flashes which are fired in rapid succession with subsets of the
cameras. Each camera records only a single photograph and the total capture time is less than the 67ms blink reflex. The
cameras and flashes are specially arranged to produce an even distribution of specular highlights on the face. We employ this
set of acquired images to estimate diffuse color, specular intensity, specular exponent, and surface orientation at each point
on the face. We further refine the facial base geometry obtained from multi-view stereo using estimated diffuse and specular
photometric information. This allows final submillimeter surface mesostructure detail to be obtained via shape-from-specularity.
The final system uses commodity components and produces models suitable for authoring high-quality digital human characters.
