Chapter 24. Fixing Photo Flaws > Removing Dust and Scratches

Removing Dust and Scratches

The Dust & Scratches filter can be a tremendous time-saver when you're doing basic cleanup on a photo, particularly an old scanned one. If you're not careful, though, it can ruin the picture by overcompensating for the spots and losing detail. The filter works by adding a slight blur, which you can carefully adjust to produce a good compromise between spots and sharpness. To use it, choose Filter, Noise, Dust & Scratches.

Figure 24.11 shows the filter's interface, applied to a very detailed scan of an old photo. As you can see, there are large chunks of dirt, as well as smaller bits of dust and at least one hair running through the picture. But it's a good, clear scan, and worth the time it will take to clean it.
