Figure 7-21. Left: The photo as it came from the camera. Right: The same photo treated with a
dose of Unsharp Mask. The change is subtle, but notice how much clearer the individual hairs in
the dog's coat are and how much better defined the eyes and mouth are.
TIP
An exception to the rule about sharpening only once is when you're converting raw im-
ages ( The Sharpen Tool ): You can usually sharpen them both in the Raw Converter and
then again as a last step in the Editor without causing problems.
If you're sharpening an image that has layers, be sure the active layer has something in it.
(Applying sharpening to a Levels Adjustment layer, for example, won't do anything.) Also,
perform any file-format conversions before sharpening. Finally, you may want to sharpen a
duplicate layer just in case you decide to undo your changes later; press Ctrl+J/ -J to create
the duplicate layer.
