Using Layer Effects - Adobe PHOTOSHOP 5.0 User Manual

284 CHAPTER 11
Using Layers
4 Use the following methods to view the
adjustment layer mask:
Alt-click (Windows) or Option-click (Mac OS)
•
the adjustment layer thumbnail to view only the
grayscale mask. Alt/Option-click the thumbnail
again to redisplay the other layers.
Hold down Alt+Shift (Windows) or
•
Option+Shift (Mac OS), and click the adjustment
layer thumbnail to view the mask in a rubylith
masking color. Hold down Alt+Shift/Option+Shift
and click the thumbnail again to turn off the
rubylith display.
Shift-click the adjustment layer thumbnail to
•
turn off the masking effects temporarily; click the
thumbnail again to turn on the mask.
Note: If you paint the adjustment layer mask with
black or gray, you can modify the boundaries and
effects of the mask (by applying a filter, for example).
Adjustment layer masks that contain only white
values are unaffected by most filters.
Merging adjustment layers
You can merge an adjustment layer with the image
layer below it, the layers in its clipping or linking
group, or all other visible layers in the image. You
cannot, however, merge an adjustment layer exclu-
sively with another adjustment layer. When you
merge an adjustment layer with the layer below it,
the adjustments become permanent and apply
only within the merged layer. (See "Merging
layers" on page 268.)
Adjustment layers whose masks contain only
white values do not add significantly to the file
size. As a result, it is not necessary to merge these
adjustment layers in an effort to conserve file
space.

Using layer effects

Adobe Photoshop includes a number of
automated effects that you can apply to layers,
including drop shadows, glows, bevelling, and
embossing. When you apply a layer effect, an
"f " icon ( ) appears to the right of the layer's
name in the Layers palette. Layer effects are linked
to the layer contents. When you move or edit the
contents on the layer, the effects are modified
correspondingly. Layer effects are especially useful
for enhancing type layers.
Note: You cannot apply layer effects to a background.
