Radial Blur

This effect produces a soft blur by simulating the effect of a zooming or rotating camera. Select the Spin blur method if you want to blur along concentric circular lines, as if rotating the camera. Select the Zoom blur method if you want to blur along lines radiating from the center. Drag the dot in the Blur Center box to change the origin of the blurring. You can also set the Amount of the blur from 1 to 100. With the Spin blur method, this value reflects the degree of rotation; with the Zoom blur method, this value reflects the intensity of the blur.
