Tony, perhaps you are not understanding my point.  The number of stops you
captured on film had NO relationship to the dynamic range of the scanner.
That's basic.  I can have the EXACT same dynamic range in the scanner, yet
have one film/exposure/development that covers 5 f-stops, and one
film/exposure/development that covers 7 f-stops.  This is because the film
it self will both have the same dMin and dMax, but will contain more/less
exposure latitude.

I completely understand the relation between f-stops and dynamic range, but
I believe it is erroneous and misleading to express the dynamic range of a
scanner in f-stops.
