Color Balance Node

The Color Balance node can adjust the color and values of an image.

Color Balance Node.

Inputs

Factor

Controls the amount of influence the node exerts on the output image.

Color

Standard color input.

Properties

Two different correction formulas could be selected.

Lift/Gamma/Gain

  • Lift

    Increases the value of dark colors.

    Gamma

    Adjusts midtones.

    Gain

    Adjusts highlights.

Offset/Power/Slope (ASC-CDL)

  • Offset

    Summand. (Adjusts the overall brightness.)

    • Basis

      Additional offset, allows to specify a negative Offset value.

    Power

    Over-all exponent. (Adjusts the midtones.)

    Slope

    Multiplier. (Adjusts the highlights.)

Outputs

Color

Standard output image.

Advanced

The Offset/Power/Slope Formula

out = (i × s + o)p

where:

  • out: The color graded pixel code value.

  • i: The input pixel code value (0 to 1) (black to white).

  • s: Slope (any number 0 or greater, nominal value is 1.0).

  • o: Offset (any number, the nominal value is 0).

  • p: Power (any number greater than 0, nominal value is 1.0).
