How Do I--EDIT A LAYER MASK

Edit a layer mask
In the Layers panel, select the layer containing the mask you want to edit.

Do one of the following:

• (CS6) Click the Mask thumbnail in the Layers panel
Select any of the editing or painting tools.


Do one of the following:


• To subtract from the mask and reveal the layer, paint the mask with white.


• To make the layer partially visible, paint the mask with gray. Darker grays make the level more transparent, lighter grays make it more opaque.


• To add to the mask and hide the layer or group, paint the mask with black. The layers below become visible.

To edit the layer instead of the layer mask, select it by clicking its thumbnail in the Layers panel. A border appears around the layer thumbnail.
