Sometimes we might need to apply sharpening to combat inherent image softness or imper fections in your lens, camera or image quality. Images that are slightly blurry due to camera shake might also benefit from sharpening. Then there are times when we want to draw attention to an area of a photo, or improve the legibility of something in the image. In each case, the aim is to improve the sharpness of your image without over-sharpening, which can require a fine eye and good judgement.
