2.8.5 CLEANUP / DENSITY UND CLIP / GAIN
Each key type provides the possibility of processing the key signal according to this
method or that one. Each imaginable result can be obtained by both methods, but
depending on the purpose, this method or that one succeeds faster. The selection,
however, should be made prior to the adjustment procedure – subsequent swit-
ching will affect the result.
Both methods enhance the characteristic curve of the key signal. The only differ-
ence is the invariant center of rotation of the characteristic curve.
Each automatic run resets all four parameters.
This method influences only one end of the key area and keeps the other one invari-
ant.
CLEANUP influences only the area of the background. Key levels are
increasingly limited to black, i.e. ”cleaned”. Noise and
slight shadows in this area will disappear.
DENSITY influences only the area of the foreground. Key levels are
increasingly limited to white to the unity value ”1”, which
corresponds to the ”dense” foreground.
