  Facial geometry and appearance capture have demonstrated tremendous success
in 3D scanning real humans in studios. Recent works propose to democratize this
technique while keeping the results high quality. However, they are still
inconvenient for daily usage. In addition, they focus on an easier problem of
only capturing facial skin. This paper proposes a novel method for high-quality
face capture, featuring an easy-to-use system and the capability to model the
complete face with skin, mouth interior, hair, and eyes. We reconstruct facial
geometry and appearance from a single co-located smartphone flashlight sequence
captured in a dim room where the flashlight is the dominant light source (e.g.
rooms with curtains or at night). To model the complete face, we propose a
novel hybrid representation to effectively model both eyes and other facial
regions, along with novel techniques to learn it from images. We apply a
combined lighting model to compactly represent real illuminations and exploit a
morphable face albedo model as a reflectance prior to disentangle diffuse and
specular. Experiments show that our method can capture high-quality 3D
relightable scans.
