1. FG White Level MASTER
The FG White Level control adjusts the gain of the FG image without compromising the quality of
the composite. If the FG seems too bright or too dark for the BG scene in the composite, use the
FG White Level control to alter the level of the FG subject rather than adjusting the FG source
level. Altering the level at the FG source can adversely affect the generation of the matte signal.
The default setting of FG White Level control is unity (100%). The range of the control is from 0%
to 125%. Clips at the output of the Ultimatte-9 prevent these levels from exceeding standard
limits.
Any offsets in the FG RED, GREEN and BLUE LEVEL controls added from the FG LEVEL menu
will be preserved as the FG Level Master control is adjusted.
2. FG Master Black MASTER
The FG Master Black control
adjusts the level of 'black' in the FG image without altering the gain
of a 100% white FG object. Adjusting the black level can often produce a more convincing
composite image, if the black levels in the BG scene differ from those in the FG.
Any offsets in the FG Black Level Red, Green and Blue Black controls added from the FG Black /
White menu will be preserved as the FG Black Level Master
control is adjusted. Clips at the
output of the color control section will clip negative values to zero.
