Range Mask and Auto Mask Tips Lightroom Classic
In this Lightroom Classic tutorial, I'll show you a couple of ways of using auto mask and range mask when you want to isolate the areas you want to adjust. These options are available in Lightroom Classic with the adjustment brush, radial filter and graduated filter.
When you check the Auto Mask box here at the bottom of the Adjustment Brush panel, it helps you keep your brush from spilling over into other areas that you don’t want the effect to appear.
Range Masks make selective adjustments easier and more accurate by using light or color as your guide.
