Channel Mixer effect
The Channel Mixer effect modifies a color channel by using a mix of the current color channels. Use this effect to make
creative color adjustments not easily done with the other color adjustment tools: Create high-quality grayscale images
by choosing the percentage contribution from each color channel, create high-quality sepia-tone or other tinted
images, and swap or duplicate channels.
[output channel]
-
[input
channel]
The percentage of the input channel value to add to the output channel value. For example, a Red-Green
setting of 10 increases the value of the red channel for each pixel by 10% of the value of the green channel for that pixel.
A Blue-Green setting of 100 and a Blue-Blue setting of 0 replaces the blue channel values with the green channel values.
[output channel]
-Const
The constant value (as a percentage) to add to the output channel value. For example, a Red-
Const setting of 100 saturates the red channel for every pixel by adding 100% red.
Monochrome
Uses the value of the red output channel for the red, green, and blue output channels, creating a
grayscale image.
Removing all Red input from the Red channel, and adding 50% of the Green channel and 50% of the Blue channel to the Red channel

Color Balance effect
The Color Balance effect changes the amount of red, green, and blue in the shadows, midtones, and highlights of an
image.
Preserve Luminosity
Preserves the average brightness of the image while changing the color. This control maintains
the tonal balance in the image.
Color Balance (HLS) effect
The Color Balance (HLS) effect alters an image’s levels of hue, luminance, and saturation.
Hue
Specifies the color scheme of the image.
Lightness
Specifies the brightness of the image.
Saturation
Adjusts the image’s color saturation. The default value is 0 which doesn’t affect the colors. Negative values
decrease saturation, with -100 converting the clip to grayscale. Values greater than 0 produce more saturated colors.
Note:
If the Color Balance Saturation control does not give you the results you want, try the Saturation control in the Fast
Color Corrector effect.
