When applying selective sharpening to a noisy low-light image in post-production, what is the specific benefit over applying a global sharpening adjustment?

When applying sharpening to a noisy low-light image in post-production, the specific benefit of selective sharpening over global sharpening is the ability to enhance desired details without simultaneously exaggerating image noise in other areas. A noisy low-light image is one captured under dim conditions, resulting in random variations in pixel brightness and color, often appearing as grain or speckles, especially in darker or smooth areas. Sharpening is an image processing technique that increases the contrast along edges in an image, making details appear clearer and more defined. Global sharpening applies this edg....
