This filter produces an image effect that simulates what you might see if you took a picture while spinning a camera in circles, or by zooming in quickly using a very slow shutter speed. You can also choose a twirling effect.
Choose Adjust > Blur > Radial Blur.
In the Blur type section, choose one of these options:
Spin: blurs pixels circularly around the image center.
Zoom: blurs pixels away from the center.
Twirl: blurs pixels in a spiraling manner.
In the Blur section, choose a Strength value. Lower values lessen the effect; higher values intensify the effect.
If you chose the Twirl option, you can then set the Twirl degrees value, which ranges from -90 to 90.
Mark the Elliptical check box if the radius should be squeezed to fit the image. If the image is square, this option will have no effect. For rectangular images, this option produces elliptical blurring; when turned off, the blurring will be circular.
In the Center section, choose the settings that affect the center of the image:
Horizontal offset %: allows you to set the horizontal center point of the blur.
Vertical offset %: allows you to set the vertical center point of the blur.
Protect center %: allows you to determine how much to diminish blurring at the image center. Higher values increase the radius of the unblurred center area.
