Thank you.

BZZZZZT.  B&W films have very LOW density ranges in the overall spectrum of
density ranges of films.  You're lucky if you find a density range of near 2
from B&W print film.  What this density range on the film represents from
the scene is a different issue.  You could have a scene density range of 11
stops, or 5 stops, both represented with the same film density range.
