246 CHAPTER 6 ERASING AND TOUCHING UP Figure 6-27. The Gaussian Blur filter Gaussian Blur can use either of two Blur methods: IIR and RLE. It really doesn t matter which one you use. They produce the same results, but switching to RLE may be slightly faster for images that are computer-generated or have large areas that are all the same color. IIR, the default, is faster for photographs. Adjust the Blur Radius (which controls the amount of blur) while watching the preview. Make sure the Preview button is checked (it should be, by default). You can scroll around in the preview window if you need to. As with most effects, the right amount of blur depends on how large (in pixels) your image is, as well as how strong you want the effect to be. Sometimes blurring too much can create an unrealistic, dreamy effect. This could be either good or bad, depending on your goal. Usually you ll want to keep the Horizontal and Vertical numbers the same (they re linked together by default), but if you ever need them to be different, you can unlink them. Tip Sometimes that tiny preview window is annoying and you want a bigger one. With Blur it s particularly obvious, since it s hard to tell the overall effect of blurring the background from viewing only a small piece of an image. GIMP can increase preview size, but it takes some fiddling. See the section on gtkrc in Chapter 12 to learn how to change preview size.
