### 7.33. Subtract Masks from Selection

The Subtract Masks from Selection command converts the layer masks of the selected layers into a selection, which is subtracted from the selection that is already active in the image.

White areas of the layer mask are selected, black areas are not selected, and gray areas are converted into feathered selections. The layer mask itself is not modified by this command.

#### 7.33.1. Activating the Command

You can access this command from the main menu through Layer → Mask → Subtract Masks from Selection.
