Radial Blur settings Spin    Controls the magnitude of the apparent rotation in the image. Type a number from 1 to 100 or drag the slider to set the value. Or, drag the solid area inside the circle. Drag clockwise to simulate slower rotation; drag counterclockwise to simulate faster rotation and produce more blurring. Quality    Higher quality creates a smoother image but takes more time. The quality differences become more pronounced when the image is enlarged or printed on standard size paper. Select Draft for the fastest redraw. Select Good for average redraw speed and quality. Select Best when image quality is most important. Centering options    These options let you set the rotation origin. Center In Image sets the origin at the center of the image. Center in Selection sets the origin at the center of a selection. “Offset from Center in Pixels” lets you type values to offset the origin from the center of the image or selection. Type vertical and horizontal offset amounts in pixels in the text boxes. Negative horizontal offsets move the center to the left. Negative vertical offsets move the center up. Positive horizontal offsets move the center to the right. Positive verti- cal offsets move the center down. Preview    Displays the effect of the current settings. Zoom Blur The Zoom Blur filter can create the effect of movement in an image, as if the scene were moving rapidly toward or away from the observer. The filter blurs along an axis perpendicular to the image. You can specify the depth, direction, and smoothness of the blur effect. This command works with all image modes except Black & White, Indexed, and Duotone. To apply zoom 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 > Zoom Blur. Adjust the settings in the dialog box, and then click OK to apply the filter. Zoom Blur settings Span    Sets the depth, (length) of the zoom effect. Type a number from 1 to 100 or drag the slider to set the value. A larger number sim- ulates a greater zoom depth and a more blurred effect.
