Colors can be selectively isolated through the use of a matte and adjusted using hue, saturation, brightness, gamma, contrast, temperature, cyan/magenta, red, green, and blue controls.

Color.

Certain parts of the image are isolated by the creation of a matte. Whatever is shown as white in the matte can be adjusted by the color controls below.

Rotates the hue of the image.

Adjusts the saturation of the image. Positive values saturate, negative values desaturate.

Adjusts the brightness of the image. Positive values brighten, negative values darken.

Adjusts the contrast of the image. Positive values increase contrast, negative values decrease contrast.

Adjusts the gamma of the image. The gamma adjustment leaves the white and black points the same and only modifies the values in-between. Positive values lighten the midtones, negative values darken the midtones.

Sets the color of the image to be either warmer or cooler. Dragging the numeric field to the right makes the image cooler (bluer) and dragging the numeric field to the left makes the image warmer (redder).

Adds either Cyan or Magenta to the image. Dragging the numeric field to the right makes the image more magenta and dragging the numeric field to the left makes the image more cyan.

Adds or subtracts red from the image.

Adds or subtracts green from the image.

Adds or subtracts blue from the image.

A matte is created to isolate areas to be color corrected. Using advanced image slicing algorithms, mattes are created using luminance, hue, saturation, average, red, green, blue, cyan, magenta, and yellow values.

Extract On selects the type of matte. Select whichever type isolates the desired values.

A matte is created based on one of the following:

A matte is created based on the luminance of the image.

A matte is created based on the hue of the image. When adjusting the Position parameter, you are selecting different hues.

A matte is created based on the saturation of the image.

A matte is created based on the average of the image’s RGB values.

A matte is created based on the image’s red values.

A matte is created based on the image’s green values.

A matte is created based on the image’s blue values.

A matte is created based on the image’s cyan values.

A matte is created based on the image’s magenta values.

A matte is created based on the image’s yellow values.

The Position value pinpoints the color values to be used in the matte. For a luminance matte, a Position value of 100 would make a white matte of the highlights and a value of 0 would make a white matte of the shadows. In the flower image below, look at how the matte varies for different Position values in a red extraction. When the Position is at a value of 100, the red flowers are shown as white in the matte.

When the Position is moved to 50, the red flowers turn black.

Increases or decreases the range of values in the matte. A low Range value indicates a narrow range of values. A high Range value indicates a large range of values included in the matte.

Blacks in the matte are made blacker by increasing this value. As the value increases, more values are clipped to black. This is helpful for getting rid of unwanted gray areas in what should be the black part of the matte.

Whites in the matte are made whiter by increasing this value. As the value increases, more values are clipped to white. This is helpful for getting rid of unwanted gray areas in what should be the white part of the matte.

Shrinks or grows the matte. Negative values shrink and positive values grow the matte.

Blurs the matte.

Does nothing to the matte.

Inverts the luminance values of the matte.
