The check box Hold Luma allows you to hold the luminance level of
the clip while adjusting a single color component. Usually, while adjust-
ing a color component, the luminance of the clip is changed as well, i.e.
changes occur in the Brightness setting, too. When this check box is
activated during the adjustment of a color component, e.g. G, instead
of adjusting the brightness parameter, the luminance of the image is set
via the remaining two values (R and B) which will be set according to
your changes while the luminance level is preserved.
7.10.4 Lift / Gamma / Gain
To the right of the Global items you can find the Lift, Gamma and
Gain items where you can adjust the individual color components in
more detail. This area provides the same sliders as the previously de-
scribed ones but for further accuracy they are split into the three con-
trast shades: lift, gamma and gain.
Figure 7-31: The detailed color settings
Use the sliders the same way as described for the global color settings.
Then you can set the values for each color component of the brighter,
average and darker parts of an image separately, for example, by alter-
ing the brightest parts of the image (highlights) while preserving the av-
erage and darkest parts (shadows).
Lift Adjusts the darker parts of the clip, i.e. the lift or black
point. Values range from -100 to +100.
Gamma Adjusts the average parts of the clip, i.e. the gamma
or mid-tones. Values range from 0.1 to 3.
Gain Adjusts the brighter parts of the clip, i.e. the gain or
white point. Values range from -100 to +100.
