Input Range

Input Min

The lower range of the input. This will be linearly mapped to 0.0 before applying the bias and gain.

RIB: float inputMin

Default: 0.0

Input Max

The upper range of the input. This will be linearly mapped to 1.0 before applying the bias and gain.

RIB: float inputMax

Default: 1.0

Clamp Input

If enabled, inputs less than inputMin or greater than inputMax will be clamped before applying the bias and gain. Clamping is performed on each color component independently. If disabled this may produce excessive results.

RIB: int clampInput

Default: 1

Remap

Bias

Adjusts the mid-tones in the inputRGB color. This is a normalized gamma correction factor. Values greater than 0.5 lighten the mid-tones in the inputRGB color, and values less than 0.5 make the mid-tones darker.

bias = 0

bias = .25

bias = .5

bias = .75

bias = 1

RIB: color bias

Default: 0.5 0.5 0.5

Gain

Lightens or darkens the highlights and dark areas from the inputRGB color. Gain is used to favor dark areas when it is less than 0.5, and it favors light areas when the gain is greater than 0.5.

gain = 0

gain = .25

gain = .5

gain = .75

gain = 1

RIB: color gain

Default: 0.5 0.5 0.5

Output Range

Output Min

The lower range of the output. Values will be linearly mapped from 0.0 to this after applying the bias and gain.

RIB: float outputMin

Default: 0.0

Output Max

The upper range of the output. Values will be linearly mapped from 1.0 to this after applying the bias and gain.

RIB: float outputMax

Default: 1.0

Clamp Output

If enabled, the final outputs will be clamped to the 0.0 to 1.0 range. This clamping is performed on each color component independently.

RIB: int clampOutput

Default: 1
