It is best to view an image at 100% to see the effects of sharpening (as well as noise reduction) accurately. If you prefer to remain at a different zoom view in the image preview area, click the disclosure triangle to the right to the word Sharpening in the Detail panel. Then, click the square icon to pick it up and click in the image preview area over the area that you would like displayed at 100% in the Details panel. This will allow you to see a small area at 100% in the panel while viewing a different view in the preview area.
