Working with Smart Filters
Now that you have a good foundation for Smart Objects, the concept of Smart Filters
shouldn't be too hard to follow. A Smart Filter is simply one of the Photoshop i lters
applied to a Smart Object layer. Filters are usually destructive—that is, any ef ect applied
to a layer becomes more dii cult to remove. When you use a Smart Filter, any i lter you
apply is not permanent. Ef ects can be toggled of and on, combined, or deleted. As you
will see in this exercise, you can work with the built-in mask of a i lter ef ect to customize
your i lter ef ects in ways that were previously not possible in Photoshop.
In this exercise, you will be applying a combination of two i lters to create an ef ect of
motion, then you will use the layer mask to rei ne the ef ect with the Brush tool.

Select the Butterl y 4 layer, and choose Filter > Sharpen > Smart Sharpen. The Smart
Sharpen dialog box appears. Change the Amount value to 200 percent and the Radius
to 1.0 ; then press OK. A dramatic sharpen ef ect is applied; the butterl y should now
show more detail.

In the Layers panel, below the Butterl y 4 layer, there is a Smart Filter listed with a
white thumbnail to the left. Immediately below that is the Smart Sharpen i lter ef ect.
These two lines were automatically added when you applied the i lter. You will now
examine how they work.

Click on the Visibility icon ( ) next to the Smart Sharpen i lter ef ect. This turns the
Smart Sharpen i lter of and allows you to view the original image. Click in the now-
empty space to toggle the i lter back on.
Clicking on the Visibility icon toggles
a i lter ef ect on and of .
You will now add a Blur i lter in addition to the Smart Sharpen i lter.
