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.

  1. Select the Blur, Sharpen, or Smudge tool.

  2. 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.

  3. 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.
