gree.
Only those objects lying within the selected absorption
range will be represented with all the available brightness
levels.
As a result, a considerable contrast enhancement is
achieved, since no brightness levels are required for non-

The higher the absorption range is se-
lected, the smaller it is set automatic-

high-absorbing objects with the highest
contrast.
