Image-based relighting represents a class of techniques that apply new lighting conditions to a scene, given a set of basis images. In this sketch we present a relighting technique that, for a single viewpoint, accurately captures the reflectance field of objects, without restrictions on their geometrical complexity or material properties. Once the reflectance field is captured, the objects can be relit under arbitrary lighting conditions. To achieve such accurate results, our method combines the strengths of both the Light Stage [Debevec et al. 2000] and environment matting [Zongker et al. 1999; Chuang et al. 2000] into a single framework.
