I'm not a designer so pardon for asking. What's the purpose of adding noise to an image?

[MoonGhost]

Noise is an artistic effect, it changes the look and feel.

A) It adds something in the blanked spaces.

B) improves visual sharpness of blurry images.

C) It works in video as well.

Also increases image file size and/or introduces compression artifacts.

[Rayid]

No worries! So, noise adds texture, reduces banding, hides artifacts, and gives images a vintage or organic feel.

It’s a small touch, but it can make images look more natural and visually appealing!

It can also massively increase the file size of the image, sometimes that can be relevant.
