Remove Dust and Specks from a Scanned Image with Photoshop Elements

Next, go to Filter > Sharpen > Unsharp Mask. If you're uncomfortable dialing in the right settings for Unsharp Mask, instead you can switch to the Elements "Quick Fix" workspace, and use the Auto Sharpen button. It still applies Unsharp Mask, but Photoshop Elements tries to determine the best settings automatically based on the image resolution.
