Note:
Rotating the outer ring of the color wheel (left) changes the hue angle (right).
To shift the colors toward a target color with gain and magnitude adjustment, drag the Balance Magnitude circle out from the center
toward the color you want introduced into the image. The farther you drag the Balance Magnitude from the center, the introduced color
is more intense. Drag the Balance Gain handle to fine-tune the intensity of the Balance Magnitude adjustment. You can make the
adjustment very subtle.
Adjusting the Balance Gain to fine-tune the Balance Magnitude setting.
The Three-way Color Corrector effect lets you make separate adjustments to the three tonal ranges using individual wheels for the
shadows, midtones, and highlights.
7. Use the Saturation control to adjust the color saturation in the image. Moving the slider to the left (lower value) desaturates the colors.
Moving the slider to the right (higher values) increases the color saturation.
Adjust color and luminance using curves
The curves adjustment of the Luma Curve and the RGB Curves effects, like the Levels sliders in the Fast Color Corrector and the Three-way
Color Corrector effects, let you adjust the entire tonal range or just a selected range of colors in a video clip. But unlike Levels, which has only
three adjustments (black level, gray level, and white level), the Luma Curve and RGB Curves let you adjust up to 16 different points throughout an
image’s tonal range (from shadows to highlights).
Opening a scope in a Reference Monitor that’s ganged to the Program Monitor lets you view the luminance, chrominance, or both values as
you make the curves adjustments. If you’re using the Vectorscope, there should be minimal green shading in the areas outside of the center of
the scope. Areas outside the center define the level of color saturation.
1. In the Effects panel, click the triangle to expand the Video Effects bin, and then click the triangle to expand the Color Correction bin.
2. Drag one of the following effects to the clip in a Timeline panel:
Adjusts primarily luminance. Keep in mind that adjusting the luminance does affect the perceived saturation of the colors.
Adjusts both color and luminance.
If a clip is selected in a Timeline panel, you can drag the effect to the Video Effects section of the Effect Controls panel.
3. In the Effect Controls panel, click the triangle to expand the Luma Curve or RGB Curves controls.
4. (Optional) Do any of the following to set preview options:
To view only the luminance values in a clip, choose Luma from the Output menu. This option affects only the preview in the Program
Monitor; it doesn’t remove the color from the video.
To display a before and after view of the clip in one monitor, select the Show Split View option. You can specify whether the split view is
horizontal or vertical by choosing from the Layout menu. You can also adjust the relative proportion of the before and after views.
5. (Optional) Click the triangle to expand the Secondary Color Correction controls if you want to correct the exposure for a specific color or
range of colors. Use the Eyedropper tool or the other Secondary Color Correction controls to specify the colors to correct.
