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).
