Color Correction
The color corrector changes the following RGB attributes of an input signal:
•
Gain
•
Offset
•
White Slope
•
Black Stretch
•
Gamma Correction
These parameters include "lock" options that make it possible for you to adjust all of the options of a
particular group in tandem, rather than separately.
White Slope and Black Stretch
The white slope is comprised of
G White Knee
,
B White Knee
,
R White Knee
, and
GBR White Knee Lock
.
Black Stretch
includes
G Black Knee, B Black Knee, R Black Knee
, and
GBR Black Knee Lock
.
Component knees determine the amount of additional gain applied to segments at the ends of the RGB
transfer functions in the look-up tables. The values displayed are a percent of the available correction. A
positive white knee increases the slope of the last 15% of RGB values, and decreases the slope of the
preceding 15%. A positive black knee parameter will increase the slope of the first 15% of the transfer
function by the amount entered and decrease the slope of the next 15%, to return to the unmodified
transfer function. Each component knee is added to the total knee (the sum cannot exceed 100%) to
produce the correction applied to the respective component.
