Median

The Median filter uses an interesting approach to rid your image of unwanted noise—it rounds the corners of things, which causes tiny specks to literally implode. As you increase the Amount setting, the filter will round the corners to a larger degree, which will make larger specks in the image blend into the surrounding image (Figures 12.11 and 12.12). What's really nice about this filter is that it doesn't make anything look blurry. I don't usually need to use settings above 2 when applying this filter.

Figure 12.11. Using the Median filter with a Radius of 1 (its lowest setting) effectively removed the small specks.
