business of creating illusions With

layer effects, you can accomplish this

in short, easy steps The Photoshop effects

that you can apply alone or in combination include

Drop Shadow, Inner Shadow,Outer Glow, Inner Glow,

Bevel and Emboss, Satin, Color Overlay, Gradient

Overlay,APattern Overlay, and Stroke.Once applied,

layer effects can be edited, hidden, or removed at any

time And best of all, when you modify layer pixels,

the effects update accordingly (they should be called

“Smart Effects”!)

In this chapter, we include generic instructions for

applying, copying, moving, and removing layer effects;

individual instructions for each effect; and finally, the

steps to save and apply effects, combined with other

Layers panel settings, as styles via the Styles panel

Applying layer effects (general info)

Layer effects can be applied to any layer (even to

edit-able type), but not to the Background They affect all

the visible pixels on a layer and update instantly if you

add, modify, or delete pixels from the layer that

con-tains them Each individual effect can be turned on or

off at any time via its own visibility icon

Layer effects are applied and edited via the Layer

Style dialog and are listed on the Layers panel below

the layer they belong to Before exploring the

indi-vidual effects, familiarize yourself with these generic

instructions

To apply layer effects (generic instructions):

1 Do any of the following:

Double-click to the right of a layer name; or for an

image layer (not a type or Smart Object layer), you

can double-click the layer thumbnail instead

Click a layer, then choose an effect from the Add

Layer Style menu at the bottom of the Layers

panel

AThree effects are applied to this editable type: Drop Shadow,

Bevel and Emboss, and Gradient Overlay.

Continued on the following page

The Layer Style dialog opens.A

2 Click an effect name on the left side, check

Preview to preview the effect in the image, then

choose settings

3. Optional: Click other effect names to apply

additional effects to the same layer

4 Click OK.

5. Edit the layer (e.g., for a type layer, edit the

type; for an image layer, add or erase some

pixels) Watch as the “smart” effect(s) update

instantly!

On the Layers panel, layers that contain effects

have this icon: Click the arrowhead next to

the icon to expand or collapse the list of effects

for that layer (B, next page)

6 To change the settings for an effect or to add

more effects to a layer, double-click the layer or the Effects listing, or double-click the effect name, which is nested below the layer name

7. To hide or show one layer effect, expand the effects list for the layer, then click the visibility icon for the effect

To hide all the effects on a layer, click the visibility icon for the “Effects” listing

➤ If you readjust the Angle for an individual effect while Use Global Light is checked, that angle will be applied to any other effects that are using the Global Light option This option unifies the lighting across multiple layer effects

➤ If you move layer pixels, any effects on the layer will also move

A In the Layer Style dialog, click the name for the layer effect that you want to

display and choose settings for (the box becomes checked automatically) The Contour presets define the effect

profile Gray areas in the thumbnail represent opaque pixels, and white areas represent transparency To close the preset picker, either double-click a contour or click in the dialog.

What kind of imagery can layer effects be

applied to?

➤ We recommend applying the layer effects that

work inward or outward from edges — Drop

Shadow, Inner Shadow, Outer Glow, Inner Glow,

Bevel and Emboss, and Stroke — to a type layer,

shape layer, or any layer imagery that’s

sur-rounded by transparent pixels.ATo isolate a

subject from its background before applying

layer effects, select an area of a layer, then press

Ctrl-J/Cmd-J (the Layer via Copy command)

➤ You can apply the Satin, Color Overlay, Gradient

Overlay, and Pattern Overlay effects either to

fully opaque layers or to layers that contain

transparency

Note: Don’t bother creating a selection before

apply-ing a layer effect Your selection will be ignored by

the Layer Style command

➤ To establish new default settings for a particular layer effect, choose the desired settings in the Layer Style dialog, then click Make Default

➤ To restore the default settings to a layer effect that you established by clicking Make Default (or to restore the factory default settings, if you didn’t establish user default settings), click Reset to Default

➤ To restore the settings that were in place in all the panels when you opened the Layer Style dialog, Alt-click/Option-click Reset (Cancel becomes Reset)

➤ Unfortunately, the only way to restore the factory default settings to all layer effects is by resetting all the Photoshop preferences Hold down Ctrl-Alt-Shift/

Cmd-Option-Shift while relaunching the program, and click Yes in the alert dialog

To hide or show an individual effect, click its visibility icon

To open the Layer Style dialog, choose an effect from the Add Layer Style menu (or double-click the layer)

Any effect that is already applied to the current layer will have a check mark.

The fx indicates that this layer contains layer effects.

B Click the arrowhead to expand or col-lapse a list of layer effects.

To hide or show all the effects for a layer, click the Effects visibility

icon

A The Layers panel for this image is shown above right: Layer effects are applied to

an image layer that contains transparency;

the underlying layer is solid white.

Applying a shadow effect

You can create a drop shadow or inner shadow with

just a few clicks of the mouse

To apply the Drop Shadow or Inner Shadow

effect:

1 On the Layers panel, double-click next to a layer

name to open the Layer Style dialog.A

2 Click Drop Shadow or Inner Shadow.

3 Choose a Distance value (in pixels) by which

you want to offset a drop shadow from the

origi-nal layer shapes,Bor for the width of an inner

shadow.C–D

➤ You can also change the position of a shadow

by dragging in the document while the dialog

is open, but be aware that this will also

repo-sition any other effects that are using the

Global Light option

Choose a Spread percentage for a Drop Shadow

or a Choke percentage for an Inner Shadow to

control where the shadow begins to fade

Choose an overall Size for the shadow (in pixels).

4 You can also change any of these settings:

Choose a Blend Mode from the menu (For a

drop shadow, we usually keep the default setting

of Multiply.)

To choose a different shadow color, click the

color swatch, then choose a color from the Color

Picker or click a color in the document with the

eyedropper (the new color previews

immedi-ately) Click OK Note: If you change the color for

an inner shadow, you may also want to change

the Blend Mode to Normal

Choose an Opacity percentage for the

transpar-ency level of the shadow (the default value is

75%, but we usually lower it)

Choose an Angle for the angle of the shadow

relative to the original layer shapes

In the Quality area, you can click the Contour

arrowhead and choose a preset from the picker

for the edge profile of the shadow (we’re usually

satisfied with the shape of the default Contour)

Check Anti-aliased to soften any jagged edges

between the shadow and the layer imagery

Adjust the Noise level The addition of noise

(speckling) can help prevent banding on print

output, but a low value is best

A The original image consists of some garden tools on one layer and a background pattern on another layer (we created the pattern via Filter > Render > Clouds).

B The Drop Shadow effect is applied

C The original image consists of editable type on one layer and a blue-gray background pattern on another

D The Inner Shadow effect is applied.

For the Drop Shadow effect, if the layer Fill

opac-ity is below 100% or the layer blending mode

isn’t set to Normal, check Layer Knocks Out

Drop Shadow to prevent the shadow from

show-ing through transparent areas on the layer

5 Click OK If you’re not satisfied with the shape of

the resulting shadow, follow the steps below

➤ To scale the effects on a layer without scaling the

other layer content, right-click the Effects listing

and choose Scale Effects, then specify the desired

Scale percentage in the dialog

Depending on the time of day and the angle of the

sun or another light source, cast shadows are either

short or elongated You can reshape a drop shadow

via the Distort command

To transform a Drop Shadow effect:

1 Apply the Drop Shadow effect (see the preceding

instructions),Aand keep that layer selected

2 To transfer the shadow effect to its own layer,

right-click the Effects listing on the Layers panel,

choose Create Layer(s) from the context menu,

then click OK in the alert dialog, if one appears

3. Click the new Drop Shadow layer.B

4 Choose Edit > Transform > Distort, drag the

han-dles of the transform box to slant the shape, then

press Enter/Return.CFor a symmetrical

perspec-tive distortion, hold down

Ctrl-Alt-Shift/Cmd-Option-Shift as you drag a corner handle Note: If

you don’t see all the handles, press Ctrl-0/Cmd-0

(zero) to enlarge the document window

➤ To limit any painting or fill changes to just the

shadow shape, on the Layers panel, activate the

Lock Transparent Pixels button

➤ To ensure that the image and shadow layers will

move and transform as a unit, Shift-click them,

then click the Link Layers button at the

bottom of the panel

A The original layer has a Drop Shadow effect.

B We clicked the new Drop Shadow layer…

C …then we elongated the shadow.

LAYER OPACITY AND FILL SETTINGS

A quick reminder from the preceding chapter: The

Opacity setting on the Layers panel controls the

opacity of layer imagery — including any layer

effects — whereas the Fill setting controls only the

opacity of layer imagery — not of layer effects

Applying a glow effect

The Outer Glow and Inner Glow effects add a soft,

airbrushed rim of color to the edges of layer imagery

or to type

To apply the Outer or Inner Glow effect:

1 Display the Swatches panel.

2 On the Layers panel, double-click a layer to

open the Layer Style dialog.Note: For the Outer

Glow effect, we recommend using a silhouetted

image layer above a solid-color layer or the

Background.A

3 Click Outer Glow or Inner Glow In the

Elements area, increase the Size value.

4 Under Structure, B–Cdo any of the following

optional steps:

To change the glow color, click the color square,

choose a color from the Color Picker (or, while

the picker is open, choose from the Swatches

panel or click a color in the document), then click

OK to exit the picker (For the gradient option,

see the next chapter.)

Change the Blend Mode.

Change the Opacity level for the glow.

To prevent banding on print output, increase the

Noise level slightly to add speckles.

5 Choose other Elements settings:

From the Technique menu, we recommend

choosing Softer for smooth color transitions.

For an Inner Glow, click Source: Center to create

a glow that spreads outward from the center of

the layer pixels (this looks good on type), or click

Edge to create a glow that spreads inward from

the inside edges of the layer imagery

Choose a Spread percentage for an Outer Glow

or a Choke percentage for an Inner Glow to

control the point at which the glow starts to

fade We keep these values relatively low

6 Choose Quality settings:

Optional: Click the Contour arrowhead and

choose a preset from the picker to add rings of

transparency to the edges of the glow

Choose a Range value to control where the glow

is applied relative to the contour

7 Click OK ( A, next page)

B We chose these Structure and Elements settings for the Inner Glow effect in the Layer Style dialog…

C …and we chose these Structure and Elements settings for the Outer Glow effect.

A The original image contains a silhouetted image of a watch above a solid-color Background.

A The Layer Style settings shown in Figures Band Con the

preceding page produced these inner and outer glow effects.

BECOMING A LAYER EFFECTS PRO

We also added the Bevel and Emboss effect — two effects

look better than one.

A total of the three layer effects — Drop Shadow, Bevel and Emboss, and Gradient Overlay — look better still.

This is plain editable type (in the Bodoni Highlight font) on

top of a pattern layer.

The Drop Shadow effect is applied.

➤ When deciding which effect or effects to use,

con-sider what kind of surface texture you want to create

Stone? Metal? Paper? Type that looks as if it’s embedded,

or embossed, into porous paper, or satin text that looks

as if it’s cast in metal?

➤ With the exception of Drop Shadow and Overlay, layer

effects usually look better, or more convincing as an

illusion, when applied in combination (see the fi gures

below)

➤ If you achieve a layer effect or combination of effects and Layers panel settings that you like, save that collection of settings as a style on the Styles panel (see pages 365–366) This can be a great timesaver

➤ While the Layer Style dialog is open, you can click

Blending Options on the upper left side, then use the options to control how the current layer blends with underlying layers (Note that the same blending mode, Opacity, and Fill controls are also available on the Layers panel.) See pages 304–305
