Manipulating Images
with Filters
Introduction
Adobe Photoshop filters are a designer's dream come true.
With filters you can turn a photograph into an oil painting or
a watercolor; you can even change night into day.
Photoshop's Filter menu includes no less than 105 highly cre-
ative filters, which can be applied once, reapplied, or com-
bined with other filters to create any effect your imagination
can dream up.
The potential combination of filters and images literally
runs into the millions. This means that Photoshop filters are
truly an undiscovered territory. As a matter of fact, the Filter
Gallery lets you view the effects of one or more filters on the
active document. This level of power gives you unbelievable
creative control over your images.
Other commands, such as the Fade command, let you
reduce the effect of the applied filter. You can even apply a
blending mode to the final image. In addition, you can utilize
a channel mask to control how the filter is applied to the
image. You could also use a black to white gradient channel
mask to slowly fade the effects of the filter from left to right.
Photoshop even lets you protect your intellectual property
by embedding a customizable watermark into the image that
is almost invisible to see, and virtually impossible to remove.
In fact, you can print an image that contains a watermark, run
it off on a copy machine and rescan it, and the watermark is
still there. Now that's protection.
Tak e a moment t o view s o m e of the various filter e ffects
that Photoshop offers. Because there are 105 filters available,

we can't show you all of them, but we think you'll enjoy
viewing the selection at the end of the chapter.

The Filter Gallery enables you to maintain complete and total control
over Photoshop's filters. In essence, the Filter Gallery gives you access

to all of Photoshop's filters and lets you apply the filters to any raster
image, while viewing a large preview of the results. The Filter Gallery
dialog box is composed of three sections—Image Preview, Filter
Selection, and Filter Controls. When you use the Filter Gallery to modify
the image, you see exactly how the image will look; there is no guess-
work involved. When you apply a filter to an image, you are physically
remapping the pixel information within the image. Photoshop contains
105 filters and the combinations of those filters are astronomical. If you
are a math wizard, you know there are over 100 million combinations
available, and that means no one has yet discovered all the ways you
can manipulate an image in Photoshop…have fun trying.

When you apply a filter to a Smart Object, the filter becomes a nonde-
structive Smart Filter. If you don't have a Smart Object, you can convert
a normal layer for Smart Filters. Smart Filters appear in the Layers
panel below the Smart Object layer, where you can show or hide them
independently. You can apply any filter to a Smart Object except Liquify
and Vanishing Point.

Not only does Photoshop's Filter Gallery let you apply and view a filter
effect, it lets you view the multiple effects of two or more filters. The
Filter Gallery has its own Layers panel, and you can have multiple filter
layers. The order of the filters influences their impact on the image, so
when you use more than one filter, try dragging the filter layer up or
down in the stack to see the different possibilities. Experiment with dif-
ferent stacking orders to create unique, eye-popping special effects.
