Filter: Smart Blur

This filter, accessible through Filter/Blur/Smart Blur, works to remove low-intensity "noise" from an image. It does this by preserving the areas where there is a sharp color contrast, such as edges, and blurring the areas where the colors are almost the same (within a tolerance set by you). As you can imagine, this is useful when treating grainy photographic images, since the grainy areas are usually only slightly different in color from the surrounding areas. The real detail of the image is largely left untouched.
