RE: Pos vs neg grain

[Tom C]

Back when I paid attention to this, the answer was generally yes, IIRC.  
Positive films tended to have finer grain than negative films.  Comparing 
Kodak and Fuji was like apples and oranges because Kodak measured their 
grain and differently than everyone else.  That made me suspect, and I in 
general shoot Velvia 50 or Provia 100F.  Back when I last checked, they were 
the finest grain films available.

Caveat... I'm remembering back over 5 years ago.   Sorry, I can't provide 
any info for B&W.

I had a lab owner emphatically contend that.."positive
film of the same ISO has finer grain than negative
film". Didn't address b&w.
We happened to be reviewing a b&w print at the time
and their existed a situation wherein the subject
couldn't be pursued (customers waiting).
I've since emailed him for a follow-up on his
recommendation that "b&w film be scanned as positive
film".
If his answer (if received) is at all decipherable,
I'll forward it.
Does anyone know or suspect what he may be talking
about?
I've, also, read the RMS charts but, their results
don't appear to be comparable.
