A method factorizing a sequence of images acquired of a scene into lighting components. The scene is illuminated by a moving light source. An appearance profile is constructed for each pixel in the sequence of images. The appearance profile is a vector representing intensities of the pixel at instances in time. The appearance profiles are factorized into a shadow component, a skylight component, and a sunlight component.
