• Shift-click the adjustment layer thumbnail to
turn off the masking effects temporarily; click the
thumbnail again to turn on the mask.
4 Edit the layer mask:
• To constrain editing to part of the mask, make a
selection. (See "Making pixel selections" on
page 103.)
• To remove the adjustment effect or fill, paint the
layer mask with black.
To display the full effect of the adjustment or fill
•
over the image layers beneath, paint the layer mask
with white.
• To partially remove the adjustment effect or fill,
paint the layer mask with gray. The extent to which
the effect or fill is removed depends on the tones of
gray you use to paint.

Merging adjustment layers or fill layers
You can merge an adjustment or fill layer several
ways: with the layer below it, with the layers in
its own grouped layer, with the layers it is linked
to, and with all other visible layers. You cannot,
however, use an adjustment layer or fill layer as the
target layer for a merge. When you merge an
adjustment layer or fill layer with the layer below
it, the adjustments are rasterized and become
permanently applied within the merged layer.
(See "Merging layers" on page 174.) You can also
rasterize a fill layer without merging it. (See
"Simplifying layers" on page 173.)
Adjustment layers and fill layers whose masks
contain only white values do not add significantly
to the file size, so it is not necessary to merge these
adjustment layers to conserve file space.
