The Gaussian Blur filter changes the color value of each pixel by applying a weighted average based on the color values of pixels within a specified distance. Color values at the edge of the specified distance influence the final color value less than closer pixels. The Average filter determines the new color value for each pixel by equally averaging all color values within the specified radius. To apply Gaussian Blur or Average blur 1 Select one or more paint objects to blur. You can select an area in one image to blur the selected area only. 2 Choose Image > Filter > Blur > Gaussian Blur or Average. 3 Specify a radius value from 0.1 to 250.0 in the Gaussian Blur dialog box, or 1 to 16 in the Average dialog box. Smaller radius values produce more subtle effects than larger ones. 4 Click OK. Depending on the size of the radius, applying a Gaussian or Average blur can take longer than other Blur filters. Motion Blur The Motion Blur filter can create the effect of linear movement. You can specify the direction and magnitude of the effect. This command works with all image modes except Black & White, Indexed, and Duotone. To apply motion blur 1 Select one or more paint objects to blur. You can select an area in one image to blur the selected area only. 2 Choose Image > Filter > Blur > Motion Blur. Adjust the set- tings in the Motion Blur dialog box, and then click OK to apply the filter and close the dialog box. Blur Blur More Average Gaussian
