Gaussian Blur
The Gaussian Blur filter allows you to soften the look of an image. Gaussian refers to the bell-shaped curve that is generated when the program applies a weighted average to the pixels. The Gaussian Blur filter adds low-frequency detail and can produce a hazy effect.
1. Do one of the following:
 Choose Effects > Blur > Gaussian Blur
 Click the Gaussian Blur button on the toolbar
2. Use the following options:
 Radius (px)
Determines the number of pixels surrounding the pixel that affect the blurring. The greater the value, the more obvious the blurring.

Min = 5, Max = 500, Default = 8.
