Color Balance Node.

Inputs

Factor

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

Color

Standard image input.

Properties

Two different correction formulas could be selected.

Lift/Gamma/Gain
Lift

Increases the value of dark colors.

Gamma

Will adjust 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).
