Choose View > 100%. The image may appear very large; you can pan the image by pressing and hold-
ing the spacebar and pushing the image around on the screen. Position the image so that you can see an
area with detail, such as one of the eyes. Note that you should be in Actual Pixel view when using most
filters, or you might not see accurate results on your screen.
Press and hold the spacebar, and click and drag on the image area to adjust the position of the im-
age in the window.

Choose Filter > Convert for Smart Filters (this step is unnecessary if you already converted your layers
into a Smart Object). If an Adobe Photoshop dialog box appears informing you that the layer is being
converted into a Smart Object, click OK. Smart Objects allow you to edit filters more freely. Read more
about Smart Objects in Lesson 12, “Using Smart Objects in Photoshop.” An icon ( ) appears in the
lower-right corner of the layer thumbnail, indicating that this is now a Smart Object.

Choose Filter > Sharpen > Unsharp Mask. The Unsharp Mask dialog box appears.
You can click and drag inside the preview pane to change the part of the image that appears there.
Unsharp masking defined
Unsharp masking is a traditional film compositing technique used to sharpen edges in an image. The Unsharp Mask
filter corrects blurring in the image, and it compensates for blurring that occurs during the resampling and printing
process. Applying the Unsharp Mask filter is recommended whether your final destination is in print or online.
