ADOBE PREMIERE PRO CS3 261 User Guide 8 Do any of the following: • To adjust color balance and saturation using color wheels, adjust the Hue Balance and Angle wheels or numeric controls in the Fast Color Corrector or Three-Way Color Corrector effect. See also "Color balance, angle, and saturation controls" on page 262. • To adjust luminance or color using a curve control, use the curve adjustments in the Luma Curve or RGB Curves effect. See also "Adjust color and luminance using curves" on page 265. • To adjust luminance by setting the black, gray, and white levels, use the levels controls in the Fast Color Corrector or the Three-Way Color Corrector effect. See also "Adjust luminance using levels" on page 266. • To adjust luminance or color using numeric controls, use the controls in the Luma Corrector or RGB Color Corrector effect. Use keyframing to animate your color correction adjustment. This is especially useful when the lighting changes in a clip. See also "About keyframes" on page 282. 9 (Optional) Apply the Video Limiter effect after you've made your color corrections to make the video signal conform to broadcast standards while preserving as much of the image quality as possible. It's recommended to use the YC Waveform scope to make sure the video signal is within the 7.5 to 100 IRE levels. See also "About the vectorscope and waveform monitors" on page 278 Quickly remove a color cast The Fast Color Corrector and the Three-Way Color Corrector effects have controls to quickly balance colors so the white, grays, and black are neutral. The adjustment that neutralizes the color cast in a sampled area is applied to the entire image. This can remove the color cast in all colors. For example, if an image has an undesirable bluish cast, when you sample an area that should be white, the White Balance control adds yellow to neutralize the bluish cast. This yellow adjustment is added to all the colors in the scene, which should remove the color cast in the entire scene. 1 Select the clip in the Timeline panel and apply either the Fast Color Corrector or the Three-Way Color Corrector effect. 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 Select the White Balance eyedropper and click to sample an area in the Program Monitor. It's best to sample an area that is supposed to be white. If you only want to affect one color or a specific range of colors in the clip, use the Secondary Color Correction controls in the Three-Way Color Corrector. 5 (Optional for the Three-Way Color Corrector only) Do any of the following: • To color balance by neutralizing a medium-gray area of the image, select the Gray Balance eyedropper and click an area that's supposed to be a medium gray. • 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.
