POV-Ray and most other ray tracers can only simulate directly, one of
these three types of illumination. That is the light which comes directly
from the light source which diffuses in all directions. The keyword 'dif-
fuse' is used in a finish statement to control how much light of this direct
light is reflected via diffuse reflection. For example:
finish { diffuse 0.7 }
means that 70% of the light seen comes from direct illumination from light
sources. The default value is diffuse 0.6.
