When using a control surface, the Encoder Sensitivity parameter in the User Prefs tab of
the Setup room let you customize the speed with which these controls make
adjustments. For more information, see “
Control Surface Settings ” on page 103.
Adjusting Contrast in the Shadows, Midtones, and Highlights
The primary contrast sliders consist of three vertical sliders, which are used to adjust
the black point, the distribution of midtones, and the white point of the image.
Each slider is a vertical gradient. Dragging down lowers its value, while dragging up
raises its value. A blue bar shows the current level at which each slider is set, while the
third number in the Output display (labeled “L”) below each color control shows that
slider’s numeric value.
Adjusting the Black Point with the Shadow Slider
The behavior of the shadows contrast slider depends on whether or not the Limit
Shadow Adjustments preference is turned on (for more information, see “
User Interface
Settings ” on page 104).
