Adjusting the Balance Gain to fine-tune the Balance Magnitude setting.
Note: 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:
Luma Curve Adjusts primarily luminance. Keep in mind that adjusting the luminance does affect the perceived
saturation of the colors.
RGB Curves Adjusts both color and luminance.
Note: 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.
