[Tig] Film Grain. Possibly a momentous question.

Trends in imaging processing of late have diminished the importance of  
film grain.

Is this a fad, or a permanent conversion of observer values?

It once was observed that film grain improved the viewer's distance  
from the subject,
such that storytelling was enhanced via this distance.  (viz.: sports  
or live / soap opera TV vs. film.)

to some extent the same could be said of temporal resolution: 24 fps  
becomes superior to 30 fps, in
the NTSC world.

Is Immediacy, and its correlates, resolution, more important than the  
slight distance from subject
that film's grain and framerate connote?

Peter Swinson held forth here on the TIG several times about  
Stochastic Resonance: the relationship
between particles (of grain for example) and images devoid of same:  
those images that included
particles were observed to be sharper.

this must be a subject for extreme study.
