The Threshold value determines how dissimilar the pixels should be before they
are eliminated. The Radius value determines the size of the area searched for dis-
similar pixels. The default values are great for tiny dots of color like the ones in
this image.
Now that the artifacts are gone, you can sharpen the image.

In the Smart Sharpen dialog box, make sure that Preview is selected, so
you can see the effect of settings you adjust in the image window.
You can drag inside the preview window in the dialog box to see different parts of
the image, or use the plus and minus buttons below the thumbnail to zoom in and
out.

Make sure Lens Blur is chosen in the Remove menu.
You can choose to remove Lens Blur, Gaussian Blur, or Motion Blur in the Smart

Motion Blur reduces the effects of blur that resulted from the camera or the subject
moving when the photo was taken.
