What Is Image Sharpening?

Image sharpening in post-processing basically means making an image sharper. Sharpening brings out more details from the edges and separates the subject from the background. It doesn’t change the resolution but rather fixes the contrast of the edges to give a more defined look to the image.

Digital images often have blur edges or shallow depth of field where a sharp edge is required. Blurry edges ruin the details of photos. In those cases, digital images need sharpening.

How much sharpness should you add to an image?

This depends on the image and the editor mostly. One needs to have experienced eyes to understand if the image is sharp enough. Usually, a clearly defined edge is good enough.

What are image smoothing and sharpening?

Image smoothing is quite different from sharpening. Image smoothing is the process of reducing the noise (or grain) in an image. On the contrary, image sharpening defines the edges of an image by giving clarity. 

When you sharpen an image, what improves?

Sharpening an image gives clarity to the image. This enhances the edge by creating a difference between the subject and the background. Clearly defined edges give more information about the image. Sharpening an image basically improves the overall visual experience of an image.
