Despeckle

The next few filters we'll explore are found under the Filter > Noise menu. The first choice in that menu is Add Noise, which is designed for adding specks to your image; the rest of the filters listed in that menu are designed for getting rid of noise. The Despeckle filter will blend the tiniest specks into the surrounding image while leaving the major detail in your image untouched (Figures 12.9 and 12.10). The only problem with this filter is that it isn't always strong enough to completely remove noise from your image. So, if you get an image with minimal noise, then you might want to give this filter a try; but when the noise in your image is considerable, then try the other options found in the Filter > Noise menu.

Figure 12.9. After applying the Despeckle filter, the single-pixel speck has changed to a light gray speck. (I doubt you can see it here.)
