Adobe Photoshop CC Classroom in a Book (2019 Release), First Edition

Before applying the Camera Shake Reduction filter

You’ll get the best results if you apply the filter to a particular part of an image, rather than

the entire image. It can be especially useful if text has become illegible due to camera shake.

To use the Camera Shake Reduction filter, open the image, and choose Filter > Sharpen >

Shake Reduction. The filter automatically analyzes the image, selects a region of interest, and

corrects the blur. Use the Detail loupe to examine the preview. That may be all you need to

do. If so, click OK to close the Shake Reduction dialog box and apply the filter.

After applying the Camera Shake Reduction filter

You can adjust how Photoshop interprets the Blur Trace, which is the shape and size of the

camera shake that Photoshop identified. You can change the region of interest or adjust its

size, adjust the Smoothing and Artifact Suppression values, and more. For full information

about the Camera Shake Reduction filter, see Photoshop Help.
