How to quickly edit layer masks in 5 simple steps
Layer masks enable you to create anything you can imagine in Photoshop. You can add a mask to a layer and use the mask to hide portions of the layer and reveal the layers below.
To easily edit and refine existing layer masks, do the following:
- In the Layers panel, select the layer containing the mask you want to edit.
- Click the Mask thumbnail in the Layers panel.
- Select any of the editing or painting tools. The foreground and background colors assume default grayscale values when the mask is active.
- 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.
- (Optional) 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. To paste a copied selection into a layer mask, Alt-click (Win) or Option-click (Mac) the layer mask thumbnail in the Layers panel to select and display the mask channel. Choose Edit > Paste and then Select > Deselect. The selection is converted to grayscale and added to the mask. Click the layer thumbnail in the Layers panel to deselect the mask channel.
