If there are no layers in the PSD file, the Advanced Image Control palette shows
only the background layer.
Blending PSD layers
The Blend Mode drop-down menu in the Layers pane lets you control how pixels
in a selected layer interact with pixels in all the layers below the selected layer. The
blend modes are similar to those in image-editing applications: They include
options such as Multiply, Color Dodge, Exclusion, and Saturation.
Showing and hiding Photoshop layers
You can view and print layers that are showing; hidden layers do not display on-
screen or in print. Advanced Image Control allows you to hide any layer, including
the background layer.
To show a layer, click the empty box icon to the left of the layer.
To show all layers, Option+Shift+click/Alt+Shift+click the empty box icon.
To hide a layer, click the eye icon .
To hide all but one layer, Option+click/Alt+click the eye icon .
If changing the blending and opacity of layers produces undesirable results, you can
revert the layers to their original state in the imported PSD file with the Revert
Layer or Revert All Layers options in the Advanced Image Control palette menu.
Modifying PSD layer opacity
A field on the Layers pane let you control the transparency of pixels on a selected
layer. You can specify a transparency from 0% (transparent) to 100% (opaque).
Working with layer masks
If layer masks are saved with PSD files, you can enable and disable the masks in the
Layers pane of the Advanced Image Control palette by Shift-clicking the
thumbnail preview of the layer mask.
Working with PSD channels
Photoshop channels store color information about images. By default, grayscale and
indexed color images have one channel, RGB images have three channels, and
CMYK images have four channels. These are referred to collectively as the default
channels. You can use the Channels pane of the Advanced Image Control palette
to show and hide all channels, to change the color and ink solidity of a selected
spot-color channel or alpha channel, and to assign spot colors to selected indexed
colors. For example, you might assign special effects such as varnishes, embossing,
and die cuts to channels.
