We present a user-assisted approach to the decomposition of a photograph into its reflectance and illumination component. Starting from a single photograph, the user guides an optimization with simple indications such as regions of constant reflectance or illumination. The resulting decomposition facilitates advanced image editing such as re-texturing.
