Color Balance

The adjustment range is (-100) - 0 - (+100) "Highlight" and "shadows" In both mode , this plugin works like Photoshop.Maybe, it is really the same as the result of Photoshop`s adjustment. "Midtones" In this mode , the result of this plugin`s adjustment is a Little bit different from Photoshop.I was not able to build an Equation to completely accord with Photoshop`s "Color Balance".However, it`s OK , because this is logically correct, too.
