Blur Filters

The Blur filters (Filter, Blur) are useful tools when you want to soften the effects, either of a filter you have just applied or of brushstrokes in the painting. Blurring can gently smooth a harshly lit portrait or, when used on a selection instead of the whole image, can throw an unwanted background out of focus, making it less obtrusive. The Blur filters are shown in Figure 14.6.

Blur, Blur More

There are two basic Blur filters: Blur and Blur More. They do exactly as their names suggest. Blur is very subtle. Blur More is only a little less so. Figure 14.7 shows a comparison of the two, against a non-blurred original. As you can see, the changes are minor. Blurring doesn't make much difference, but it can smooth out wrinkles in a portrait or soften a hard edge.
