advanced gray balance

The Advanced Gray Balance calibration is necessary if no satisfactory standard Gray Balance can be found. While the standard Gray Balance adjusts the shape of simple gamma curves, the Advanced Gray Balance can adjust the RGB curves to any shape via the LUT file.

When doing an Advanced Gray Balance calibration, the approach is to twist the red, green, and blue curves iteratively, so that the entire printed gray scale appears neutral to the human eye.
