Holo-Relighting performs volumetric relighting on a single input portrait image, allowing users to individually control (1) lighting effect via an environment map, (2) camera viewpoint and (3) head pose. It is highly expressive and can render complex illumination effects on in-the-wild human faces with accurate view consistency (a). Controls are well disentangled to produce a realistic rendering of moving shadows cast by a point light while rotating the head (b). Practical photographic applications such as shadow diffusion (softening) are also made feasible with our system (c).
