Revealing Layers With Clipping Masks - Adobe Photoshop CS6 User Manual

Revealing layers with clipping masks

A clipping mask lets you use the content of a layer to mask the layers above it. The masking is determined by the content of the bottom or base
layer. The non-transparent content of the base layer clips (reveals), the content of the layers above it in the clipping mask. All other content in the
clipped layers is masked out.

You can use multiple layers in a clipping mask, but they must be successive layers. The name of the base layer in the mask is underlined, and the
thumbnails for the overlying layers are indented. The overlying layers display a clipping mask icon.
The Blend Clipped Layers As Group option in the Layer Style dialog box determines whether the blending mode of the base affects the whole
group or just the base. (See

layer above it that you want to include in the clipping mask (the pointer changes to two overlapping circles
Select the first layer above the base layer in the Layers panel, and choose Layer > Create Clipping Mask.
3. To add additional layers to the clipping mask, use either method in step 2, and work your way upward one level at a time in the Layers
panel.
Note: If you create a new layer between layers in a clipping mask, or drag an unclipped layer between layers in a clipping mask, the layer
becomes part of the clipping mask.
Layers in the clipping mask are assigned the opacity and mode attributes of the base layer.
Remove a layer from a clipping mask
Do one of the following:
Hold down Alt (Windows) or Option (Mac OS), position the pointer over the line separating two grouped layers in the Layers panel (the
pointer changes to two overlapping circles
In the Layers panel, select a layer in the clipping mask, and choose Layer > Release Clipping Mask. This command removes the
selected layer and any layers above it from the clipping mask.
