When Adobe introduced the Filter Gallery in Photoshop, it finally gave designers the ability to view the effects of multiple filters applied to a single image While this changed forever how we apply filters to an image, there is one more creative way to work—Blending Modes For example, you can make a copy of an image, apply a separate filter effect to each layer, and then use the Blending Modes option to create

a totally different image While this is not a new technique, the results

of combining two or more layers together, each with a different filter effect, can produce quite stunning results

Blending Modes and

Filter Effects

Work with Blending Modes and

Filter Effects

Open an image

Select the layer containing the

image you want to modify

Press Ctrl+J (Win) or A+J (Mac)

to create a copy of the selected

layer

Select the layers one at a time and

apply a different filter to each

layer

Select the top layer

Click the Blending Modes list

arrow and experiment with the

various blending options

In this example, the Cutout and

Find Edges filters were used on

the separate layers, and then

combined with the Linear Light

Blending Mode

Did You Know?

You can use the Opacity option to

fur-ther control the final image If the

blending effect appears a bit too

intense, simply lower the opacity of the

top or bottom layer to change the

intensity of the filter effects

The Pattern Maker filter (optional plug-in) lets you create your own dis-tinctive patterns, based on image information in the active document, or clipboard memory Since the pattern is based on sample data, it shares the visual characteristics of the sample For example, if you sample an image of a cloudy sky, the Pattern Maker generates a tile-like pattern that is different from the sample but still retains the elements of a cloudy sky You can even generate multiple patterns from the same sample

Building Custom

Patterns

Build Custom Patterns

Open a document

Select the Layers panel, and then

select the layer you want to use to

create a pattern

Click the Filter menu, and then

click Pattern Maker.

If the filter is not available, go to

www.adobe.com, search for the

filter, and then download it

Select the Rectangular Marquee

tool on the toolbox, and then

select a portion of the image

Select the portion of the image you

want to use to generate an image

Click Generate to create a random

pattern based on the selected

sample

Click Generate Again to generate

another random pattern

IMPORTANT All the generated

patterns are stored in the Tile

History box, located on the bottom

right of the Pattern Maker dialog

box

Select from the available Tile

Generation options:

◆ Use Clipboard As Sample Uses

the pixel information contained

in the Clipboard as the

tile-generating pattern

◆ Use Image Size Creates a tile

pattern the size of the original

◆ Width Enter a value (1 to 800),

or click the black triangle and

drag the slider left or right to

define a width

◆ Height Enter a value (1 to 800),

or click the black triangle and

drag the slider left or right to

define a height

◆ Offset Click the list arrow, and

then click None, Horizontal, or

Vertical

◆ Amount Enter a percentage

value (1% to 100%), or click the

black triangle and drag the

of 1, 2, or 3

◆ Sample Detail Enter a value

from 3 to 21, or click the black

triangle and drag the slider left

or right

◆ Show Click the list arrow, and

then select between the

generated sample and the

original image

◆ Tile Boundaries Select the

check box to view the tile

edges in the preview window

Click on the color box, and then

select an alternate color

Scroll through your tile patterns

using the left/right arrow keys

underneath the Tile History

preview Stop when you see the

pattern you want

Click OK.

IMPORTANT When you click

OK, the Pattern Maker filter

over-writes the original image, so it's a

good idea to make a copy of the

image in a separate layer before

using the Pattern Maker filter

Using Pattern Maker

Custom patterns can be generated from any RGB, Grayscale, CMYK,

or Lab Color mode graphic image In addition, when you create a pattern, the original image is overwritten with the new pattern, so you can use the generated pattern, reopen the Pattern Maker filter, and then create new patterns from the pattern you just created

For Your Information

Photoshop's Fade command is a one-shot chance to change your mind

For example, you've just applied the Find Edges filter to an image You like the look but the effect is too dramatic What you really want to do

is tone down the effect Unfortunately, filter effects don't fade like a gradient; they are simply applied, all or nothing, to the image You could create a copy of the original layer, apply the effect to the copy, and then use Layer transparency and blending mode options to merge the effect with the image, but there's an easier way Just use the Fade command

Using the Fade

Command

Use the Fade Command

Open a document

Select the Layers panel, and then

select the layer to which you want

to apply a filter

Click the Filter menu, and then

click Filter Gallery.

Apply any of Photoshop's filters to

the active image

Click OK.

Click the Edit menu, and then click

Fade The Fade command includes

the name of the applied filter

IMPORTANT The Fade

command must be executed

before performing any other

command Once you execute

another command, the ability to

modify the last filter is lost

Change the Opacity and Mode

settings until you see the effect

you're after

Click OK.

Did You Know?

You can use the Fade command with

almost any filter or drawing tool Every

time you draw, use a command or use

a filter, the Fade command gives you a

one-shot chance to fade and blend

When you apply a filter to an image, Photoshop applies the filter equally to the entire image Unfortunately, that might not be what you had in mind For example, you might want to apply the Gaussian Blur fil-ter to a portion of the image In that case, Photoshop's selection tools come to the rescue The primary purpose of making a selection is to define a work area, and when you select an area before applying a fil-ter, the only area impacted by the filter will be the selected area

Controlling Filters

Using Selections

Photoshop's filters can be applied to any raster image In addition, fil-ters can be controlled with the use of selections You can use any of Photoshop's selection tools to define a working area However, simple selections are limited in what they can do Although the edge of selec-tions can be modified by feathering, the inside area of the selection is completely selected What if you want to apply a filter in a completely different way? For example, what if you want to apply a filter that is stronger on the right side of the image, and slowly tapers off from left

to right? In that case a simple selection won't help, but a Channel mask will do exactly what you need

Using a Channel

Mask to Control

Filter Effects

Use a Channel Mask to Control

Filter Effects

Open a document

Click the Channels panel, and then

click the Add New Channel button.

Select the Gradient tool on the

toolbox, click a linear gradient,

select the default foreground and

background colors of black and

white, and then drag left to right

across the new channel mask

Photoshop creates a horizontal,

black to white channel mask

Select the Layers panel, and then

select the layer containing the

image you want to modify
