Unlinking layers and layer masks
By default, a layer is linked to its layer mask, as
indicated by the link icon between the thumbnails
in the Layers palette. The layer and layer mask
move together in the image when you move either
one with the move tool.
You can unlink the layer from its layer mask by
clicking the link icon. Unlinking the two lets
you move them independently and shift the mask
boundaries separately from the layer. To re-
establish the link, click between the layer and
layer mask thumbnails.
Viewing layer masks
By default, the layer mask channel does not appear
in the image. You can view and edit the contents of
the mask or temporarily turn off its effects. You
can also change the display options for the mask.
To select and display the layer mask channel:
Do one of the following:
Alt-click (Windows) or Option-click (Mac OS)
•
the layer mask thumbnail to view only the
grayscale mask. The eye icons in the Layers palette
are dimmed because all layers are hidden. To
redisplay the layers, again Alt/Option-click the
layer mask thumbnail, or click an eye icon.
Hold down Alt+Shift (Windows) or
•
Option+Shift (Mac OS), and click the layer mask
thumbnail to view the mask on top of the layer
in a rubylith masking color. Hold down
Alt+Shift/Option+Shift and click the thumbnail
again to turn off the color display.
To turn off the layer mask temporarily:
Do one of the following:
1
Press Shift and click the layer mask thumbnail in
•
the Layers palette.
Choose Layer > Disable Layer Mask.
