Trang 1Using clipping masks
When layers are formed into a clipping mask, the
content of the bottommost layer, called the “base”
layer, clips (limits the display of pixels on) the
layers above it The mode and opacity of the base
layer — which can be a type, image, Smart Object, or
shape layer — is applied to the clipped layers
To create a clipping mask:
1 Position the base layer so it is stacked directly
below the successive layers to be clipped
2 Do one of the following:
Shift-click the layers to be clipped (not the base
layer), then press Ctrl-Alt-G/Cmd-Option-G.A–B
Alt-click/Option-click the line between two layers
(the pointer becomes two overlapping circles)
Right-click a layer to be clipped (not the base
layer) and choose Create Clipping Mask
The base layer name has an underline; the
thumbnail for each clipped layer has a
down-ward-pointing arrow and is indented
3. Optional: To include more layers in the mask,
either repeat the preceding step or restack other
layers between existing layers in the mask.C–D
➤ All the layers to be put in a clipping mask must
be listed consecutively When creating a clipping
mask of layers in a group, all the layers (including
the base layer) must be part of the group
Note: When a layer is released from a clipping mask,
any masked layers above it are also released
To release a layer from a clipping mask:
Do either of the following:
Alt-click/Option-click the line below the layer
to be released
Click a layer to be released (not the base layer),
then press Ctrl-Alt-G/Cmd-Option-G
To release an entire clipping mask:
Alt-click/Option-click the line above the base
layer
➤ To merge all the layers in a clipping mask into a
base image layer and apply the clipping effect to
the result, click the base layer, then press Ctrl-E/
Cmd-E
D The type (base) layer is clipping the four image layers.
A The original image contains five layers (An editable type layer is obscured by the image layers.)
B Four layers are selected.
C We pressed Ctrl-Alt-G/Cmd-Option-G
The clipped layers are now indented and the base layer name (“SKI”) is underlined.

Linking layers
Layers that are linked together will move as a unit
in the document window and drag-and-drop as a
unit to other files If you align, distribute, or
trans-form (e.g., scale or rotate) a linked layer, your edits
will also be applied to the layers it’s linked to
To link layers:
1 On the Layers panel, select two or more layers
(Ctrl-click/Cmd-click to select nonconsecutive
layers).A–B
2 Click the Link Layers button at the bottom
of the Layers panel A link icon appears to the
right of that layer and the layers it’s linked to.C
➤ To unlink a layer, click the layer, then click the
Link Layers button The link icon disappears
➤ To deactivate a link temporarily, Shift-click the link icon for a layer A red X appears over the icon (To reactivate the link, Shift-click it again.)
To move layers that are linked:
1 Click a linked layer
2 Hold down the V key to spring-load the Move
tool, drag in the document window, then release the V key.D
➤ Don’t link any layers to the Background, because you won’t be able to move them
➤ To align or distribute multiple layers, see page 247
DWe moved the linked image layers to the left, while the base layer (the type layer) stayed put.
AThis image contains multiple layers (and a clipping mask).
B We selected four layers (they happen to be
in a clipping mask) To link them, we will click the Link Layers button.
C When a linked layer is clicked, the link
icon displays for that layer and the layers
it’s linked to.

Creating Smart Object layers
A Smart Object layer is created when you convert
one or more layers in a Photoshop document to a
Smart Object It is also an option when you open,
paste, or place an AI (Adobe Illustrator), PDF, PSD,
or Camera Raw file into a Photoshop document If
you double-click the thumbnail for a Smart Object
made from Photoshop layers, a separate document
opens in Photoshop, containing the embedded layers,
whereas if you double-click the thumbnail for a Smart
Object made from imported contents, the embedded
file opens in the creator application In either case,
when you edit, save, and close the new window, your
changes will appear in the Photoshop document (To
edit a Smart Object layer, see page 310.)
To create a Smart Object layer by converting
existing Photoshop layers:
1 Open a Photoshop document.
2 Select one or more layers on the Layers panel
(such as an image or type layer)
3 Right-click a selected layer and choose Convert
to Smart Object (this command is also available
on the Layers panel menu).A–B
To open a PSD, AI, PDF, or TIFF file as a Smart
Object layer in a new Photoshop document:
1 In Photoshop, choose File > Open as Smart
Object Locate and click a PSD, AI, PDF, or TIFF
file, then click Open
2. For an AI or PDF file, the Open as Smart Object
dialog opens.CChoose Thumbnail Size: Fit Page
and a Crop To option, then click OK A Smart
Object layer appears in a new document
To create a Smart Object layer from a
Camera Raw file:
1 From Bridge, open a photo into Camera Raw.
2. Apply any needed adjustments, then hold down
Shift and click (or just click) Open Object (see
page 86) The image appears as a Smart Object
layer in a new Photoshop document
To create a Smart Object layer from an AI or
PDF file by using the Paste command:
1 In Illustrator, copy art by pressing Ctrl-C/Cmd-C
2 Click in a Photoshop document, then press
Ctrl-V/Cmd-V The Paste dialog opens.DClick
Paste As: Smart Object, then click OK A Vector
Smart Object layer appears on the Layers panel
A We selected four layers.
C This dialog opens when you use the Open as Smart Object command to open an AI or PDF file into Photoshop.
D This dialog opens when you paste an AI or PDF file into Photoshop.
B The Convert to Smart Object com-mand combined the layers into one Smart Object layer.
All Smart Object layers have this icon
in the thumbnail.

You can use the Place command to place files of
many formats into a Photoshop document, such as
an AI or PDF file
To place a file into Photoshop as a Smart
Object layer:
1 Optional: Open a document in Photoshop.
2. Go to Edit/Photoshop > Preferences > General
and check Resize Image During Place to allow
the image to be scaled automatically and Place
or Drag Raster Images as Smart Objects to
have it arrive as a Smart Object layer Click OK
3 Do either of the following:
Choose File > Place, locate and click a file, then
click Place
In Mini Bridge, click the thumbnail for the
file to be placed, then from the Tools menu,
choose Place > In Photoshop (Or in Bridge,
choose File > Place > In Photoshop.)
4. For an Illustrator or PDF file, the Place PDF
dialog opens.AChoose a Thumbnail Size to
preview the file For a multipage PDF file,
choose the desired page Also choose a Crop To
option (to exclude any white areas outside the
artwork, choose Bounding Box)
5 Click OK The art appears in a bounding box in
the current document or in a new Photoshop
document
6. To transform the placed art, do any of these
optional steps:
To scale it, drag a handle on the bounding box
(Shift-drag to maintain the aspect ratio).B
To reposition it, drag inside the bounding box
To rotate it, position the pointer outside the
bounding box (two-headed arrow), then drag
➤ To undo the last transformation, use Undo
7 Double-click inside the bounding box, or
click the Commit Transform button on the
Options bar, or press Enter/Return.C The art
becomes a Smart Object layer
➤ If you change your mind, you can delete the
placed art before accepting it by pressing Esc
➤ For another way to create a Smart Object, drag
an object or group from an Illustrator
docu-ment window into a Photoshop docudocu-ment
window, then follow steps 6–7, above
A The file previews in the Place PDF dialog.
C When we accepted the object, it became an embedded Smart Object layer (We added a drop shadow effect to it
in Photoshop; see pages 356–357.)
B Reposition and transform the placed object, if desired, then double-click inside it to accept it.

Editing and replacing Smart Objects
To apply some types of edits to a Smart Object layer,
such as Smart Filters (see pages 320–324), blending
mode and opacity changes, and layer effects, you
simply click the layer first Edits that change pixel
data, however, such as those made by the
paint-ing, healpaint-ing, sharpenpaint-ing, and cloning tools, can’t
be made directly to a Smart Object layer (try it,
and you’ll get an alert prompt about rasterizing the
layer; click Cancel) To make those types of edits,
you double-click the Smart Object layer thumbnail
first The embedded object opens in a temporary new
document in Photoshop, in the creator application
(Illustrator), or in the Camera Raw dialog When you
close the temporary window or dialog, your changes
will appear in the Photoshop document The original
file, from which the Smart Object layer was created,
remains unchanged
To edit a Smart Object layer:
1 Double-click the Smart Object layer thumbnail
If an alert regarding saving changes appears,
click OK If the PDF Modification Detected
alert appears next,A ★click “Discard Changes,
Preserving Illustrator Editing Capabilities,”
then click OK (don’t worry… the “changes” are
internal and inconsequential)
If the Smart Object layer contains one or more
Photoshop layers, a separate document will open
in Photoshop, containing those layers; if it
con-tains imported content, that content will open in
a document in the creator application; and if it’s
a Camera Raw image, the photo will open into
the Camera Raw dialog
2 For a Camera Raw file, adjust the settings, then
click OK For any other type of Smart Object,
edit the temporary document, save it without
changing the file name or location (press Ctrl-S/
Cmd-S), and then close it Your edits will display
in the Smart Object layer in Photoshop
➤ When you place vector art as a Smart Object into
a Photoshop document, it stays as vector art
When you output the Photoshop file, the vector
art is rendered at the resolution of the printer
RASTERIZING A SMART OBJECT LAYER
If you rasterize a Smart Object layer (convert it to a standard image layer), the contents of the embedded
fi le become inaccessible, and some edits, such as Smart Filters, are applied For this reason, we recom-mend copying the Smart Object layer fi rst by using the New Smart Object via Copy command (see above)
Then to rasterize the duplicate layer, right-click it and choose Rasterize Layer
There are two ways to duplicate a Smart Object layer
If the duplicate is linked to the original Smart Object layer, any pixel edits made to the original embedded file will automatically appear in the copy, and vice versa This is useful, say, if you want to apply identi-cal pixel edits to both the original and duplicate but apply a different Smart Filter or transformation, or different opacity, mask, or layer style settings If the duplicate isn’t linked to the original, you will be able
to rasterize the copy, while keeping the original as a Smart Object layer
To duplicate a Smart Object layer:
1 Click a Smart Object layer.
2. Do either of the following:
To create a duplicate of the layer that is linked
to the original Smart Object layer, press Ctrl-J/
Cmd-J Pixel edits to the original will appear in the copy, and vice versa (A–B, next page)
To create a duplicate of the layer that isn’t linked
to the original, right-click the layer and choose
New Smart Object via Copy Edits made to the
original Smart Object layer won’t affect the copy, and vice versa (C, next page)
A new Smart Object layer appears in the Layers panel, bearing the same name as the original layer, and by default, the word “copy” is added
A This alert dialog will appear if you try to edit a Smart Object that was created from an Adobe Illustrator file.
Trang 6
Via the Replace Contents command, you can swap existing Smart Object content with a different file
Or if you open the creator application and edit the original file that a Smart Object was created from (not by double-clicking the Smart Object thumbnail), you will need to use the Replace Contents command
to update the embedded file Any transformations, filters, or layer style settings that were applied to the Smart Object layer are applied to the replacement content
To replace the contents of a Smart Object with another file:
1 Right-click a Smart Object layer (not the thumb-nail) and choose Replace Contents.The Place dialog opens
2. Locate a replacement file (either the same file that you have edited separately or an altogether
new file), then click Place Respond to any dialogs
that open (e.g., the Camera Raw dialog or the Place PDF dialog) The new image appears in the Smart Object layer
Photoshop layers that are converted to a Smart Object become embedded in the layer, and are acces-sible for editing only in the temporary document that opens when you double-click the layer thumbnail
If you need to, however, you can bring a copy of an embedded layer back into your document by follow-ing these steps
To reclaim embedded Photoshop layers from
a Smart Object:
1 In Photoshop, double-click a Smart Object layer
thumbnail, then click OK if an alert appears The embedded file opens in a separate document tab
2. Via the Arrange Documents menu, display both documents With the window for the embedded file active, drag a layer from the Layers panel into the original document window Or to copy multiple layers, Ctrl-click/Cmd-click the ones you want to copy first
3 Close the window for the embedded file (Any
Smart Filters or layer styles that you applied to the Smart Object layer won’t be applied to the copies.)
4. Optional: Delete the Smart Object layer.
A We duplicated a Smart Object layer via the Ctrl-J/
Cmd-J shortcut, then double-clicked one of the layers.
B The Smart Object opened in a temporary window
in Illustrator, and we changed the color of the
laundry basket to green In the Photoshop
docu-ment, the change registered in both Smart Objects
C Here we copied the layer using the New Smart
Object Via Copy command, then edited one of them
in Illustrator The change appeared only in that layer.
