Description

We are attempting to digitize the mural at the royal tomb of Amenophis III, one of the pharaohs of ancient Egypt. When photographing the mural, two strobe lights with umbrellas were used to provide uniform illumination. However, it was difficult to illuminate uniformly. We tried to correct this non-uniform illumination by applying an illumination model in which a strobe and an umbrella were assumed as a point light source located at a long distance. The illumination model was verified for model mural images with white patches and with uniform backgrounds instead of white patches.<br>
