In typical cases of back and side lighting, although the surface of a 3-dimensional
subject facing the camera becomes dark, a portion is usually strongly lighted. Even

darker portions, on occasion, the brighter portions can become overexposed and
difficult to see. In some instances, this effect can even be enhanced to produce a
special photographic composition, but for a generally more attractive result,
perform as follows. First use the Lumisphere and measure by standard method,
then determine exposure from the mean value (same technique as used for
Observatorial Scenes).
