We can’t really sharpen an image any more than it already is. If it wasn’t sharp when captured, there’s nowhere the information needed can come from later on. What we can do is create the illusion of sharpness by exaggerating contrast along edges in the image. This added contrast makes the edges stand out more, making them appear sharper. For images destined for print the actual amount of sharpening required for optimum image quality is usually a little more than what looks good on the screen.

Hi Susie, I use unsharp tool in Adobe Photoshop all the time, especially for cannon photos that are much more softer in texture, it really works good and does not makes a photo very digitized. Thanks for reminder, Anna

Thanks for the comment. It’s true that Cannon lenses, especially the cheaper one’s tend to make a softer texture on the photos.
