A reflectance map relates image intensities to surface orientation for given reflectance function, viewpoint and illumination direction. It is usually possible to construct a reflectance map for a surface even under complicated illumination conditions though it may be necessary to measure the intensities empirically as the relation is frequently too complex to be modelled analytically. See also Intrinsic Images.
