Smoothing Brush [U]
Mainly used for smoothing skin. It unifies skin’s colors while retaining its structure, so that the edit stays natural-looking. The Intensity setting sets how strong the smoothing is. Detail preservation sets to what extent details are preserved.
To erase part of the mask, use
Remove from Mask mode, which you can switch to in the Brush Parameters group. The brush parameters can be forced to be the same in both modes, or allowed to be different – to change this, use
Shared Brush Settings. The Diameter, Opacity, Density, and Blur settings work similarly as they do for the retouching tools.
After choosing a mask, use the slider here to set its intensity in the range from 0 to 100 percent.
