644 Chapter 23 Color Correction
Parameters
This node displays the following control in the Parameters tab:
Weight
The default R, G, and B values are set according to the human eye’s sensitivity to color,
but you can balance the colors differently to push a certain channel. The default values
are:
• R = .3
• G = .59
• B = .11
Mult
The Mult node multiplies the R,G, B, A, or Z channels. To uniformly increase the red,
green, blue, and alpha channels, use the Fade node. To affect red, green, blue, but leave
alpha at the same amount, use Brightness.
Parameters
This node displays the following controls in the Parameters tab:
Color
The value by which the incoming R, G, and B channel pixels are multiplied.
alpha
The value by which the incoming alpha channel is multiplied.
depth
Multiplying the Z value does not necessarily add a Z channel like the Add node.
Saturation
The Saturation node changes the saturation value of an image. Unlike the Monochrome
node, Saturation increases or decreases the saturation of the image weighing all color
channels equally.
Note: You can also use Monochrome to desaturate an image, giving different weights to
each of the color channels.
