Add natural photo grain or match existing grain

When I’m enhancing old images sometimes they look too smooth and digital, and it would be helpful to have an ai film grain option. thanks

Have you tried hifi enhance, as the other models tend to get more cartoony removing noise and outlining edges. If you turn down the parameters then it actually does a good job of making a higher rez version of the noise.

The older version of it in gigapixel even had filmlike color noise but that has been cleaned up in photoai.
