 Shadow Sat.: This parameter controls the saturation in the shadows of your image.
You can selectively desaturate the shadows on your image to create deeper looking
blacks and to eliminate inappropriate color in the shadows of your images for a more
cinematic look.
Master Contrast Controls
Three additional parameters also affect image contrast. For more information on
contrast adjustments, see “
Using the Primary Contrast Controls ” on page 166.
 Master Lift: Unlike the primary Shadow contrast slider, the Master Lift parameter only
functions as an add or subtract operator, making an overall luma adjustment to the
entire image regardless of how the Limit Shadow Adjustments control is set. For
more information on lift adjustments, see “
Adjusting the Black Point with the Shadow
Slider ” on page 168.
 Master Gain: This parameter works exactly like the primary Highlight contrast slider,
adjusting the white point while leaving the black point at its current level and scaling
all of the midtones in between the two.
 Master Gamma: This parameter works exactly like the primary Midtone contrast
slider, adjusting the distribution of midtones between 0 and 100 percent.
Advanced Tab
This tab contains another set of parameters for adjusting each of the three primary
color channels within each of the three tonal zones. Additionally, there are a set of
Printer Points controls for colorists who are used to optical color grading for film.
