| Color Balance | |||||
| ************* | |||||
| The Color Balance node can adjust the color and values of an image using two different | |||||
| correction formulas. | |||||
| The *Lift, Gammma, Gain* formula uses *Lift*, *Gamma*, and | |||||
| *Gain* calculations to adjust an image. *Lift* increases the value of dark | |||||
| colors, *Gamma* will adjust midtones, and *Gain* adjusts highlights. | |||||
| The *Offset, Power, Slope* formula uses *Offset*, *Power*, | |||||
| and *Slope*: ``out = (i * s + o) ^ p`` | |||||
| where: | |||||
| ``out`` | |||||
| The color graded pixel code value. | |||||
| ``i`` | |||||
| The input pixel code value (0=black, 1=white). | |||||
| ``s`` | |||||
| Slope (any number 0 or greater, nominal value is 1.0). | |||||
| ``o`` | |||||
| Offset (any number, nominal value is 0). | |||||
| ``p`` | |||||
| Power (any number greater than 0, nominal value is 1.0). | |||||
| Factor | |||||
| Controls the amount of influence the node exerts on the output image | |||||
