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
A radial color offset from the white center (changes the overall image Hue).
Power
Over all exponent.
Slope
Multiplier.

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).
