Blur filters and effectsThe blur filters and effects are useful for retouching images. They smooth transitions by averaging the pixels next to the hard edges of defined lines and shaded areas in an image. Gaussian Blur Quickly blurs a selection by an adjustable amount. Gaussian refers to the bell-shaped curve that is generated when Adobe Photoshop applies a weighted average to the pixels. This filter adds low-frequency detail and can produce a hazy effect. Radial Blur Simulates the blur of a zooming or rotating camera to produce a soft blur. Choose Spin, to blur along concentric circular lines, and then specify a degree of rotation; or Zoom to blur along radial lines, as if zooming in or out of the image, and specify an amount from 1 to 100. Blur quality ranges from Draft for the fastest but grainy results; or Good and Best for smoother results, which are indistinguishable except on a large selection. Specify the origin of the blur by dragging the pattern in the Blur Center box. |
