Here you will drag and drop a layer, multiple layers, or a layer group from the Layers panel of a source document into a target document.. Click in the source document window, then on t

Drag-copying layers between files

via the Layers panel

So far, you have learned how to drag and drop layers

with the Move tool and create layers from file

thumb-nails Here you will drag and drop a layer, multiple

layers, or a layer group from the Layers panel of a

source document into a target document An

advan-tage of this method is that if the source file contains

multiple layers, you can control which ones are

copied Here, as with the Move tool method, pixels

that lie outside the live canvas area are included

To drag-copy a layer between files via the

Layers panel:

1 Open the source and target documents On the

Arrange Documents menu on the Application

bar, click one of the 2 Up icons.A

2 Click in the source document window, then on

the Layers panel, click the layer, Background, or

layer group that you want to duplicate, or

Ctrl-click/Cmd-click multiple layers

3 Drag your selection from the Layers panel of the

source document into the target document B

A On the Arrange Documents menu on the Application bar, click a 2 Up icon.

B After clicking in the source document window, we are Shift-dragging a layer group from the Layers panel of that

document into the target document window.

SELECTING A LAYER UNDER THE POINTER

To quickly select a layer that contains nontrans-parent pixels below the pointer, choose the Move tool Check Auto-Select on the Options bar, choose Group or Layer from the menu, then click an image area in the document

(or Shift-drag the selection to make the new

imag-ery appear in the center of the target document)

The new layer(s) will be stacked above the

previ-ously selected one.A

4 If the source document has a different color

profile than the target document, the Paste Profile

Mismatch alert dialog will appear Click Convert

or Don’t Convert, then click OK

An alert will also appear if the source and target

documents have a different bits-per-channel

setting Click Yes to accept the change in image

quality (or click No to call the whole thing off)

5 Either close the source document or click the

Consolidate All (first) icon on the Arrange

Documents menu

6 Optional: With the Move tool (V), reposition

the new layer

Or to scale the new layer, choose the Move tool

and check Show Transform Controls on the

Options bar If you can’t see all the handles, press

Ctrl-0/Cmd-0 to change the document zoom level

Shift-drag a corner handle on the bounding box,

then press Enter/Return to accept the new size

A When we released the mouse, the duplicate layer group appeared in the center of the target document.

CREATING A NEW DOCUMENT FROM

A LAYER

To quickly create a new document from a layer, click the layer, then from the Layers panel menu, choose Duplicate Layer The Duplicate Layer dialog opens From the Document menu, choose New, enter a name for the new document in the Name fi eld, then click OK Save the new fi le

A We began by opening some theme-related images, just to see how they would

look together and to get our creative juices flowing We decided to use the photo

of a burlap texture as the background for a montage.

One effective way to create a composite image is by

adding layers to a target file that contains a white or

solid-color Background, a photograph of a texture,

or a screened-back image You can scale or move the

image layers individually to create a pleasing

compo-sition, and fade the side of any layer by applying

a gradient to its layer mask, as we show you here

To fade the edge of a layer using a gradient

in a layer mask:

1 Open several documents, one of which is to

be used as a background (target) image for the

whole composition.AThe target image should

be the largest of the bunch To prevent any scale

discrepancies, make sure all the images have the

same resolution

2 Follow the instructions on pages 238–239, page

240, or pages 242–243 to drag and drop the

source imagery into the target document,

includ-ing scalinclud-ing the new image layers with the Move

tool, if necessary.B

3 Save the target image and close the others.

4 Click one of the new image layers, then click the

Add Layer Mask button at the bottom of the

Layers panel (A, next page) Keep the layer mask

thumbnail selected

5 Choose the Gradient tool (G or Shift-G)

Click the Gradient picker arrowhead on the Options bar, then click the “Black, White” gradi-ent (If you don’t see this preset, choose Reset Gradients from the picker menu, then click OK

in the alert dialog.) Also click the Linear Gradient button on the Options bar

6 In the document window, start dragging

hori-zontally or diagonally from where you want the complete fadeout to be, and stop dragging where you want the image to remain fully opaque (B, next page) Hold down Shift while dragging

to constrain the angle to an increment of 45°

The gradient will fill the layer mask, and the imagery on that layer will be partially hidden (C–D, next page)

➤ To redo the fade effect, make sure the layer mask thumbnail is still selected, then drag in the document again with the Gradient tool (drag in a new direction or start dragging from a new position)

7 Repeat steps 4–6 for other layers you want to

partially mask

Fading the edge of a layer via a gradient in a layer mask

B We dragged layers from some other documents onto our target image, which contains a photo of burlap We resized and repositioned the new layers, and also rotated two of them.

D This is the Layers panel for the final image, which is shown at left.

C We also created a layer mask for the “WALL” layer, then dragged in

the document with the Gradient tool, in a different direction.

A Next, we created a mask for the “BLUE”

layer, and kept the layer mask thumbnail

selected

B We chose the Gradient tool and the “Black, White” preset To hide the edge of the imagery on the “BLUE” layer, we dragged a short distance to the left, starting from outside the canvas area

(The black areas in a mask hide layer pixels Note the black areas

in Figure D, below.)

HIDING A SEAM WITH A BRUSH

You can edit a layer mask using the Brush tool, a basic Photoshop technique that is described on page 169

REMOVING AREAS OF A MASK WITH A BRUSH

B The right edge of the “BLUE” layer is partially hidden by a gradient that we applied to the layer mask (above left) To reveal

more of the texture of the blue butterfly, we chose a Soft Round brush and an Opacity of 55% for the Brush tool, and are

painting with white as the Foreground color to partially remove the mask (above right).

A The edge of an image layer in this document is partially hidden by a gradient that we applied to the layer mask We want

to eliminate the noticeable seam We chose the Brush tool, a Soft Round brush, an Opacity value of 100%, and black as the

Foreground color We made the brush very large, clicked the layer mask thumbnail, and are dragging downward in the image

(above left) With a couple of quick swipes of the brush, the seam is gone (above right).

Aligning and distributing layers

Similar to the way you might align objects in a

draw-ing program, via buttons on the Options bar, you can

align the visible parts of one layer to another layer,

or align multiple layers to one another

To align layers to one another:

1 Choose the Move tool (V), then check Auto

Select and choose Layer on the Options bar.

2 Click one image or type layer, then Ctrl-click/

Cmd-click one or more additional layers.A

3 Click one of the six align buttons on the Options

bar (use tool tips to identify them).B–C

➤ To align layers to the edges of a selection, create

the selection before following the steps above

The distribute buttons equalize the spacing among

multiple selected or linked layers You must select

three or more layers first

To equalize the spacing among layers:

1 Choose the Move tool (V), then check Auto

Select and choose Layer on the Options bar.

2 Click a layer, then Ctrl-click/Cmd-click at least

two other layers

3 Click one of the six distribute buttons on the

Options bar.D–E

➤ Oops! You clicked the wrong button? Choose the

Undo command before applying a different one

E We clicked Distribute Horizontal Centers.

C We clicked Align Bottom Edges.

A We chose the Move tool and we selected four layers.

B These are the align buttons on the Options bar

Align Top Edges

Align Vertical Centers

Align Left Edges

Align Horizontal Centers

Align Bottom Edges

Align Right Edges

Distribute Top Edges

Distribute Vertical Centers

D These are the distribute buttons on the Options bar.

Distribute Left Edges

Distribute Horizontal Centers

Distribute Bottom Edges

Distribute Right Edges

Auto-Align Layers

By dragging with the Clone Stamp tool, you can

clone all or part of an image from one layer to

another in the same document or between

docu-ments This tool is useful for creative montaging,

commercial retouching, and video editing The Clone

Source panel lets you keep track of up to five

differ-ent source documdiffer-ents (represdiffer-ented by a row of

but-tons at the top of the panel); reassign new sources;

clone repeatedly from the same source; and

trans-form the source pixels before or as you clone them

To use the Clone Stamp tool and the Clone

Source panel:

1 Open one or more RGB documents to be used

as source imagery, and create or open a target

document

2 Choose the Clone Stamp tool (S or Shift-S)

From the Options bar, choose a Soft Round

brush, a Mode, an Opacity of 100% (to start

with), and a Flow percentage, and check Aligned

Optional: If you have a stylus and tablet, you

can activate the Tablet Pressure Controls Opacity

button and/or the Tablet Pressure Controls

Size button on the Options bar.★

Optional: If the source file contains adjustment

layers and you want the Clone Stamp tool to

ignore their effects when sampling, activate the

Ignore Adjustment Layers When Cloning

button

3 Display the Clone Source panel ABy default,

the first source button is selected Check Show

Overlay and Auto Hide, then set the Opacity to

around 35–50% so you’ll be able to preview the

source as an overlay (a faint version of the source

layer) If you want the overlay to display only

within the brush cursor, check Clipped.

4. In the target document, create a new blank layer

5 Click the source document tab From the Sample

menu on the Options bar, choose which part of

the document is to be cloned: Current Layer,

Current & Below, or All Layers For either of the

first two options, also click a layer

6. Alt-click/Option-click an area in the image to set

the source point.BThe source file and layer will

be assigned to, and will be listed below, the first

source button on the Clone Source panel

7 Click the target document tab.

8 To position the clone, move the pointer over the

image without clicking Adjust the tool diameter

by pressing [ or ], then start dragging to make the cloned pixels appear (A, next page) The overlay will disappear temporarily (because you checked Auto Hide), then will reappear when you release the mouse (For other ways to transform the overlay, see the next page.)

9 To clone from another document, click the

second source button at the top of the Clone Source panel, then repeat steps 4–8 Or to switch

to a different clone source, click its button

Beware! The Clone Source panel keeps the links

active only while the source documents are open

If you close a source document, its link to the Clone Source panel is broken!

➤ To use the Clone Stamp tool to retouch imagery within the same document, see pages 276–277

B With the Clone Stamp tool, we Alt-click/Option-click

in a source document.

A Using the Clone Source panel, you can transform the clone overlay and switch between multiple sources.
