Fill layers do not have any effect on the layers
underneath them. The fill layer options are solid
color, gradient, or pattern. Once you create an
adjustment or fill layer, you can easily edit the
settings, or dynamically replace it with a different
adjustment or fill type.
When you create an adjustment layer, its effect
appears on all the layers below it. This lets you
correct multiple layers by making a single
adjustment, rather than making the adjustment
to each layer separately. Adjustment layers can be
applied and edited only in Photoshop; however,
they can be viewed in ImageReady. When you
apply an adjustment layer to a layer set, Photoshop
adds the new adjustment layer in the layer set
above the existing layers.
For more information, see "Making color
adjustments" in online Help.
To confine the effects of an adjustment layer to
a group of layers, create a clipping group
consisting of these layers. You can place the
adjustment layers in or at the base of the clipping
group. The adjustment will be confined to the layers
inside the set. (See "Creating clipping groups" on
page 218.) Alternatively, you can create a layer set,
and have the set use any blending mode other than
Pass Through.

Creating adjustment layers or fill layers
Adjustment layers and fill layers have the same
opacity and blending mode options as image
layers and can be rearranged, deleted, hidden,
and duplicated in the same manner. By default,
adjustment layers and fill layers have layer masks,
as indicated by the mask icon to the left of the layer
thumbnail. If a path is active when you create the
adjustment or fill layer, a layer clipping path is
created instead of a layer mask. When an
adjustment layer or fill layer is active, the
foreground and background colors default to
grayscale values so you can easily edit the mask.
You can also specify a color
Adjustment layers
adjustment type for an adjustment layer.
Depending on your choice, the dialog box for
the selected adjustment command may appear.
The adjustment layer takes the name of the
adjustment type and is indicated in the Layers
palette by a thumbnail linked to a partially filled
circle. By painting the adjustment layer, you can
apply the content to just portions of the under-
lying layers.
For more information, see "Making color
adjustments" in online Help.
The fill layer takes the name of
Fill layers
the fill type and is indicated by a color, pattern,
or gradient icon to the left of the thumbnail.
Fill layers are primarily used with layer clipping
paths. For example, when you create a new layer
clipping path, it gets filled with a solid color by
default. You can later choose to change it to a
gradient or pattern fill layer. At times, you may
also want to create a new color, pattern, or
gradient layer independently of the shape tools.
