The Shake Reduction filter detects, then resharpens, edges in a photo that were blurred due to slight shaking of the camera. The filter produces better quality results on indoor shots of a static subject taken in good natural lighting with a slow shutter speed and no flash, or on indoor or outdoor photos taken with a long focal length. The photos should contain few bright highlights and minimal noise.

Improvements to the Shake Reduction filter include a new check box that disables or enables Artifact Suppression, as well as controls for adjusting the length or direction of a blur trace path. You can compare and adjust the Smoothing and Suppression settings for any pair of blur trace regions via sliders in a loupe. The dialog preview provides support for retina displays, and the preview on large monitors is also improved.
