Blur, sharpen, and smudge images
The Blur and Sharpen tools affect the focus of pixels.
The Blur tool lets you emphasize parts of an image by selectively
blurring the focus of elements. The Sharpen tool is useful for repairing
scanning problems or out-of-focus photographs. The Smudge tool lets
you gently blend colors.
Select the Blur, Sharpen, or Smudge tool.
Set brush options in the Property inspector:
- Size
- Sets the size of the brush tip.
- Edge
- Specifies the softness of the brush tip.
- Shape
- Sets a round or square brush tip shape.
- Intensity
- Sets the amount of blurring or sharpening.
Smudge options
- Pressure
- Sets the intensity of the stroke.
- Smudge Color
- Allows you to smudge using a specified color at the beginning
of each stroke. If this option is deselected, the tool uses the
color under the tool pointer.
- Use Entire Document
- Smudges using color data from all objects on all layers.
If this option is deselected, the Smudge tool uses colors from the
active object only.
Drag the tool over the pixels you want to sharpen, blur,
or smudge.

Hold down Alt (Windows) or Option
(Mac OS) to change from one tool behavior to the other.
