Chris The way this is normally achieved at present is to set up a series of Noise Patterns. These patterns are created using values 2, 4, 6, 8 - Gaussian Noise. The Noise is in these patterns is ideally blurred by a factor of 2 to 4 pixels. A 45 degree Motion Blur can be used for this, simulating the offset of film grain. This grain pattern, noise plus slight blur, is filled onto the channel, and blended (Faded) using Soft Light or Overlay blend. There is a slight levels adjustment taking off the top and bottom 1% or - this eliminates the "scum dot" in the highlight and shadow of the mask. I will get together a visual sample for you and link to it when i get time.
