100 % magnification.

Effects
The Effects tab can be used to stylize the image. It is used to add
photographic imperfections that were more typical with film-based
cameras. You can choose to simulate film grain or apply a post
crop vignette to the edges.

Double-click the Zoom tool to switch to 100% magnification.
It's easiest to accurately judge grain at a 100% view.
2.
Set grain to a value of 15 and a size of 35 to create a filmic type
noise in the image.
