In this paper, we present a lighting design framework for
near-diffuse real objects, starting from a set of prerecorded
photographs of an object under various lighting conditions.
Light sources are placed at fixed positions around an object,
for which the intensities are to be determined. Using exist
ing digital imaging software, the lighting designer paints
the desired illumination distribution on a photograph of an
object. This painted-on illumination is used to determine
the light intensities which produce a shading of the real ob
ject matching the desired illumination distribution. Certain
areas in the painted image can be favored among others by
weighting their importance in the optimization algorithm.
