To save a selection to a new alpha channel
1 Create a selection.
2 Choose Select Save Selection.
3 Choose New from the Save To list box.
If you want to specify a name, type a name in the Name box.
Alpha channels are pixel based, therefore, any path-based selections are saved
as pixel-based selections.
If you do not specify a name, the new channel is named incrementally with
the previous channel: Alpha 1, Alpha 2, and so on.
You can also save a selection to a channel by clicking the Save Selection As
Channel button in the Channels panel.
To combine a selection with an existing alpha channel
1 Create a selection.
2 Choose Select Save Selection.
3 Choose a channel from the Save To list box.
4 In the Operation area, enable one of the following options:
• Replace Mask — replaces the channel with the current selection
• Add to Mask — combines the current selection with the chosen channel
• Subtract From Mask — subtracts the current selection from the chosen channel
The “head” channel (the outline with eyes
and beak subtracted) is loaded and
intersected with the rough “face” selection.
This step removes the eyes, beak, and
background portion. The resulting selection
is saved to the “face” channel.
