Bell-Shaped Spread
Setting a bell shape is often a good starting point to create a more realistic-looking
grain. Here we have a non-uniform distribution with different amounts of grain in the
red, green, and blue channels.
In both examples, the grain’s power has been exaggerated to show the effect a
bit better.

The LightTrim node
Light Trim Node Introduction
This node emulates film scanner light trims. By design, this node works best with logarithmic
data, such as the images stored by Cineon, Arri, or Blackmagic RAW files. When logarithmic
data is provided, the Light Trim node can be used to increase or decrease the apparent
exposure level of the image.
