Sharpening or retouching.

Sharpness is a combination of two factors, resolution and sharpness.

The resolution is the number of pixels in the image file.

The higher the resolution of the image, the more pixels it has and the sharper it is.

Sharpness is the contrast obtained on an outline.

Sharpening is therefore a technique for increasing the sharpness of an image.

The actual resolution does not change.

To increase the sharpness of an image, you must increase the sharpness.

To make the image look sharper, you need to add edge contrast.
