Of the three stages in a sound sharpening workflow – capture sharpening, creative sharpening, and output sharpening – creative sharpening is the stage that has the most impact. The goal of creative sharpening is to give an image a specific look and feel. There are at least three things creative sharpening can do for your images.
One, creative sharpening can prioritize; it can direct attention to specific areas of an image.
Two, creative sharpening can enhance; qualitative aspects of images like texture and line, can be amplified to produce stronger responses.
Three, creative sharpening can be used to accentuate different qualities of light; a great deal of detail is carried by the luminosity component of color and changing it changes the overall appearance of light within the image.
Used consistently creative sharpening can produce a distinctive style that is more easily recognizable to viewers. (Remember, sharpening is a way to enhance details and it may also be used with its counterpart blurring to make effects appear even stronger by comparison.)
