How To Sharpen An Image

Most images can benefit from sharpening to address three main issues: decrease image blur, increase text legibility, and drawing attention to your subject. The sharpness of your image is affected by changing the acutance which controls the contrast of the edges of an image. The higher the acutance, the more defined the image is. Sound confusing? Don't worry, just fire up PaintShop Pro and keep reading to learn how to sharpen an image.
