AutoFacer provides a very powerful color enhancement feature, allowing you to reduce or boost the color saturation of your image while leaving skin tones largely unchanged. It's great if you have images with people where the overall color is either too weak or too strong. Normally simply adjusting the overall saturation would give faces an artificial coloring, but using the non-skin tone slider provides powerful color adjustment without distorting any face or skin tones.
