Step 1
The “Output” menu allows you to view adjustments in the Program monitor in different formats. “Composite” is the final result, “Luma” is to view the tonal values, “Mask” is a display of the alpha matte, and "Tonal Range" is a display of the shadows, midtones and highlights.
-
Step 2
You can view the “Tonal Range Definition” in Master, Shadows, Midtones or Highlights modes. Each of these has a corresponding “Hue Angle,” “Balance Magnitude,” “Balance Gain” and “Balance Angle.” Drag the sliders to the left or right to adjust the values of each.
-
Step 3
The “Three-Way Hue Balance and Angle” also has three color wheels. The one on the left is for the shadows, the middle one is for the midtones and the one on the right is for the highlights. When you select “Master” from “Tonal range”, only one wheel will appear instead of three.

Step 4
"Auto Black Level" will raise the black levels in a clip, resulting in lighter shadows.
-
Step 5
"Auto White Level" will lower the white levels in a clip, resulting in darker highlights.
-
Step 6
"Auto Contrast" will apply both the "Auto Black Level" and "Auto White Level" simultaneously, making both the highlights appear darker and the shadows appear lighter.
-
Step 7
The outer two “Input Levels” sliders map the black point and white point to the settings of the "Output" sliders. The middle "Input" slider adjusts the gamma in the image by moving the midtone and changing the intensity of values of the middle range of gray tones without dramatically altering the highlights and shadows.
-
Step 8
The “Output Levels” will map the black point and white point input level sliders to specified values. The "Output" sliders are set by default to 0, where the shadows are completely black, and to level 255, where the highlights are completely white. Changing these values can result in an increase or decrease of the overall contrast.
