2 Select Master, Shadows, Midtones, or Highlights to select the areas of the
image that you want to modify.
3 Select Main, Red, Green, or Blue to select the channel that you want to
work with.
4 Do one of the following:
■ Position the cursor on the black slider below the histogram. Set the
level until the value that you want to use as the lower limit for the
color range appears in the Minimum field.
This darkens the shadow areas.
■ Position the cursor on the white slider below the histogram. Set the
level until the value that you want to use as the upper limit for the
color range appears in the Maximum field.
The brightness in the highlight areas increases.
5 To cancel the changes, select Reset in Tools Options.
Output Sliders
The sliders on the Output levels bar below the histogram contain the Output
level controls. Use these controls to set the range of colors in the image.
The white slider on the right sets the maximum value for the range. The black
slider on the left sets the minimum value for the range.
The Output slider remaps pixel values produced by the input level. Values at
0 are remapped to the minimum, values at 1 are remapped to the maximum,
and values in between are linearly interpolated. The output slider background
is a linear ramp of the same color as the selected channel: gray, red, green, or
blue.
You can also set the maximum and minimum limits for the color range by
entering the values in the Output fields on either side of the histogram.
To reduce contrast with the Output sliders:
1 From the Tools tab, drag the CC Histogram from the Color Correction
folder to the dependency graph in the Schematic view.
