Lift

Lift uniformly lightens or darkens the entire image, altering the shadows, midtones,

and highlights by the same amount. This node has four parameters:

Â Lift: Adjusts the red, green, and blue channels simultaneously, for an overall change

to image brightness.

Â Red Lift: Adjusts the red channel only, enabling color correction based on a lift

adjustment for that channel.

Â Green Lift: Adjusts the green channel only, enabling color correction based on a lift

adjustment for that channel.

Â Blue Lift: Adjusts the blue channel only, enabling color correction based on a lift

adjustment for that channel.

Maximum

Averages adjacent pixels together (how many is based on the Brush Size parameter), to

produce a single, larger pixel based on the brightest value in that pixel group. Larger

values result in flattened, almost watercolor-like versions of the image. This node is also

useful for expanding the white areas and smoothing out grayscale images that you’re

using as mattes. This node has one parameter:

Â Brush Size: Defines how many pixels are averaged into a single, larger pixel.

Extremely large values result in progressively larger, overlapping square pixels of

uniform color, emphasizing lighter pastel-like tones in the image.

Minimum

Averages adjacent pixels together (how many is based on the Brush Size parameter), to

produce a single, larger pixel based on the darkest value in that pixel group. Larger

values result in flattened, darkened versions of the image. This node is also useful for

expanding the black areas and smoothing out grayscale images that you’re using as

mattes. This node has one parameter:

Â Brush Size: Defines how many pixels are averaged into a single, larger pixel.

Extremely large values result in progressively larger, overlapping square pixels of

uniform color, emphasizing darker, muddier tones in the image.

Printer Lights

Provides Red, Green, and Blur parameters for color correction that work identically to

the Printer Points controls in the Advanced tab of the Primary In room. For more

information, see “Printer Points Controls” on page 205.

Saturation

Raises or lowers overall image saturation, making the image more or less colorful. This

node has one parameter:

Â Saturation: The default value of 1 produces no change. 0 is a completely desaturated

image, while the maximum value of 10 produces an excessively saturated, hyper-

stylized version of the image.
