We present a practical solution to the problem of single-image relighting of paintings and drawings. Our interactive method can relight arbitrary shapes by using shading proxies. Our approach is based on a shading-ratio image that takes into account the colors used by the artist to convey shading information. We demonstrate the effectiveness of our solution on a variety of artistic styles, including paintings with strong brush strokes and unconventional shading encodings, drawings, and other types of artwork. Our method is the first to perform relighting of paintings and drawings and, in addition to relighting, estimates smooth normal and depth maps from images.
