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.
Pedestal
Adjusts an image by adding a fixed offset to the image’s pixel values. Use this control with the Gain control
to increase an image’s overall brightness.
Gain
Affects the overall contrast ratio of an image by adjusting brightness values by multiplication. The lighter
pixels are affected more than darker pixels.
RGB
Lets you adjust the midtone values, contrast, and brightness of each color channel individually. Click the
triangle to expand the options for setting the gamma, pedestal, and gain of each channel.
•
Red Gamma, Green Gamma, and Blue Gamma
Adjusts the red, green, or blue channel’s midtone values without
affecting black and white levels.
•
Red Pedestal, Green Pedestal, and Blue Pedestal
Adjusts the tonal values in the red, green, or blue channel by
adding a fixed offset to the channel’s pixel values. Use this control with the Gain control to increase the channel’s
overall brightness.
•
Red Gain, Green Gain, and Blue Gain
Adjusts the red, green, or blue channel’s brightness values by multiplication
so that lighter pixels are affected more than darker pixels.
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.
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.
