Copying layer masks
You can copy a layer mask to an alpha channel or copy a channel to a layer mask. The name of a layer mask in the Channels panel reflects the name of the layer ([Layer Name] [Layer Mask]). Although you cannot change the name of a layer mask, it automatically updates if you change the layer name.
To copy a layer mask to a channel
1
Right-click a layer mask in the
Channels panel, and choose
Duplicate.

In the
Duplicate Channel dialog box, enable the
New Alpha Channel option.
You can also copy a channel to an existing channel, so that the existing channel is replaced. To do this, enable the Replace Existing Alpha Channel option, and choose the existing channel from the list box.
