Abstract
Surface normal measurement from an inexpensive camera, and how far it can be pushed toward metric results. Work in progress, illustrated with a normal map of a fourteenth-century inlaid metal bag from Northern Iraq produced for a Courtauld Gallery exhibition – no 3D model, yet the surface can be virtually relit to bring out the finest man-made marks.
