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%.
Master
Alters the brightness and contrast of all channels when you change the shape of the curve. Bowing the curve
upward lightens the clip and bowing the curve downward darkens the clip. The steeper sections of the curve represent
portions of the image with greater contrast. Click to add a point to the curve and drag to manipulate the shape. You
can add a maximum of 16 points to the curve. To delete a point, drag it off the graph.
Red, Green, and Blue
Alters the brightness and contrast of the red, green, or blue channel when you change the shape
of the curve. Bowing the curve upward lightens the channel and bowing the curve downward darkens the channel. The
steeper sections of the curve represent portions of the channel with greater contrast. Click to add a point to the curve
and drag to manipulate the shape. You can adjust up to a maximum of 16 points on the curve. To delete a point, drag
it off the graph.
Secondary Color Correction
Specifies the color range to be corrected by the effect. You can define the color by hue,
saturation, and luminance. Click the triangle to access the controls.
Note: Choose Mask from the Output menu to view the areas of the image that are selected as you define the color range.
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.
End Softness
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.

Three-Way Color Corrector effect
(32-bit) The Three-Way Color Corrector effect lets you make subtle corrections by adjusting a clip’s hue, saturation,
and brightness for the shadow, midtones, and highlights. The effect has a histogram that displays the image’s
luminance. You can further refine your adjustments by specifying the color range to be corrected by using the
Secondary Color Correction controls.
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 the shadows, midtones, and highlights (Tonal
Range).
Show Split View
Displays one part of the image as the corrected view and the other part of the image as the
uncorrected view.
