To color balance by neutralizing a black area in the image, select the Black Balance eyedropper and click an area
that’s supposed to be black.
The Gray Balance control adjusts the sampled area to become a neutral gray and the Black Balance control adjusts the
sampled area to become a neutral black. Like using the White Balance control, these adjustments affect all the colors
in the clip.
Note: You can also click the color swatch next to the eyedroppers and use the Adobe Color Picker to select a sample color.

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.

Color balance, angle, and saturation controls
The Fast Color Corrector and the Three-Way Color Corrector effects offer Hue Balance and Angle color wheels and
a Saturation control for balancing color in your video. Color balance is just what its name implies, balancing the red,
green, and blue components to produce the desired color of white and neutral grays in the image. Depending on the
desired effect, you may not want the color balance in a clip to be completely neutral. Perhaps you want an intimate
family scene to have a warm (reddish) color cast or maybe the scene in your crime documentary requires a cool
(bluish) color cast.
