Center Defines the central color in the range that you’re specifying. Select the Eyedropper tool and click anywhere on
your screen to specify a color, which is displayed in the color swatch. Use the + Eyedropper tool to extend the color
range, and use the - Eyedropper tool to subtract from the color range. You can also click the swatch to open the Adobe
Color Picker and select the center color.
Hue, Saturation, and Luma Specify the color range to be corrected by hue, saturation, or luminance. Click the triangle
next to the option name to access the threshold and softness (feathering) controls to define the hue, saturation, or
luminance range.
Soften Makes boundaries of the specified area more diffuse, blending the correction more with the original image. A
higher value increases the softness.
Edge Thinning Makes the specified area more sharply defined. The correction becomes more pronounced. A higher
value increases the edge definition of the specified area.
Invert Limit Color Corrects all colors except for the color range that you specified with the Secondary Color Correction
settings.

RGB Color Corrector effect
The RGB Color Corrector effect adjusts the color in a clip by applying adjustments to the tonal ranges that you define
for the highlights, midtones, and shadows. The effect lets you make tonal adjustments to each color channel
individually. You can also specify the color range to be corrected by using the Secondary Color Correction controls.
For more information about using the RGB Color Corrector effect, see the video tutorial, Tips & Tricks: Color
Correction, on the
Videomaker Magazine website .
Output Lets you view adjustments in the Program monitor as the final results (Composite), tonal value adjustments
(Luma), display of the alpha matte (Mask), or a tritone representation of where the shadows, midtones, and highlights
fall (Tonal Range).
Show Split View Displays the left or upper part of the image as the corrected view and the right or lower part of the
image as the uncorrected view.
Layout Determines whether the Split View images are side by side (Horizontal) or above and below (Vertical).
Split View Percent Adjusts the size of the corrected view. The default is 50%.
Tonal Range Definition Defines the tonal range of the shadows and highlights using threshold and falloff controls:
• Shadow Threshold Determines the shadow’s tonal range.
• Shadow Softness Determines the shadow’s tonal range with falloff.
• Highlight Threshold Determines the highlight’s tonal range.
• Highlight Softness Determines the highlight’s tonal range with falloff.
Choose Tonal Range from the Output menu to view the highlights, midtones, and shadows as you adjust the Tonal
Range Definition controls.
Tonal Range Specifies whether the color correction is applied to the entire image (Master), the highlights only,
midtones only, or shadows only.
Gamma Adjusts the image’s midtone values without affecting black and white levels. Use this control to adjust images
that are too dark or too light, without distorting shadows and highlights.
