Tony - are you around?  Tony mentioned something about different grain being
more or less visible in different areas of the film.  I thin it was in response
to a comment I made about how variable the grain is in T400CN.  Grain in
shadows is very coarse, while in highlights it's virtually non-existent.
 I think it had something to do with which emulsion layers were most sensitive
to which intensities of light and therefore what got removed in processing?
