Make quick luminance corrections

The Fast Color Corrector and the Three‑Way Color Corrector effects have automatic controls for making quick adjustments to the luminance in a clip. For a video on correcting color and luminance with the Fast Color Corrector, see www.adobe.com/go/learn_dv_tutorial_fastcolor.

  1. Select the clip in a Timeline panel and apply either the Fast Color Corrector or the Three‑Way Color Corrector. See also Apply effects to clips.
  2. In the Effect Controls panel, click the triangle to expand the Fast Color Corrector or the Three‑Way Color Corrector controls.
  3. (Optional) Select the Show Split View option if you want to view a before and after comparison of your adjustment in the Program Monitor. You can specify whether the split view is horizontal or vertical by choosing from the Layout pop‑up menu. You can also adjust the relative proportion of the before and after views.
  4. Click any of the following buttons to quickly adjust the luminance to broadcast standards:
    Auto Black Level
    Raises the black levels in a clip so the darkest levels are above 7.5 IRE. A portion of the shadows is clipped and the intermediate pixel values are redistributed proportionately. As a result, using Auto Black Level lightens the shadows in an image.

    Auto Contrast
    Applies both the Auto Black Level and Auto White Level simultaneously. This makes the highlights appear darker and shadows appear lighter.

    Auto White Level
    Lowers the white levels in a clip so the lightest levels do not exceed 100 IRE. A portion of the highlights is clipped and the intermediate pixel values are redistributed proportionately. As a result, using Auto White Level darkens the highlights in an image.
