Apple Color 1.5 - Manual (Page 248)

• 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
Contrast Adjustment Explained .
• 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 .
• Master Gain: This parameter works exactly the same as the primary Highlight contrast
slider, adjusting the white point while leaving the black point at its current level and
scaling all the midtones in between the two.
• Master Gamma: This parameter works exactly the same as the primary Midtone contrast
slider, adjusting the distribution of midtones between 0 and 100 percent.
