Task 4 How to Apply a Radial Blur

A radial blur is an interesting effect that blurs an image in toward a center point or rotates it around a center point. The effect is similar to the photography technique of making a zoom lens time exposure that creates a tunnel effect in toward the subject. This is a good way to create emphasis on a central subject or image area and to control the composition as a whole.

2. Set the Amount Slider

Drag the Amount slider to control the degree of blur being applied to the image.

3. Set the Blur Method

Select either Spin or Zoom to determine whether the blur rotates around a center point in the image or zooms straight into the image.

4. Set the Quality Setting

Select Draft, Good, or Best as the Quality mode, keeping in mind that the higher the quality, the longer it takes to apply the effect. Note that higher quality does not affect the file sizejust the amount of time it takes to display the image.
