ADOBE PREMIERE PRO CS3 262 User Guide 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. See also "Specify a color or range of colors to adjust" on page 271 "Fast Color Corrector effect" on page 311 "Three-Way Color Corrector effect" on page 318 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 the Timeline panel and apply either the Fast Color Corrector or the Three-Way Color Corrector. See also "Apply an effect to a clip" on page 244. 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. See also Correct video color, easily 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. April 1, 2008
