Hi Harvey--

So according to your summary of the discussion on the ColorSync list 
they decided that the artifacts being discussed were caused by 
scanner noise in dense areas. Certainly a well-known phenomenon.  I 
on the other hand was referring to an instance where I caught myself 
erroneously attributing the effects of film grain to scanner noise. 
As far as I can tell we were talking about two different things.
