I don't think the dynamic range of chromogenic B&W is nearly as great as
silver B&W.  Note that since both chromo and silver B&W is film, it is 'wet
darkroom' until the scanning stage.  Its true that 'Zone System' includes
the work done on the print itself, but the goal of Zone System printing is
to have a negative that has enough contrast range to be printed 'straight'
on #2 or #3 grade paper.  So IOW the neg manipulation techniques:
(monochromatic filtering for improved MTF of the lens),  Push/pull
exposure/dev, all  are very useful tools in generating a negative that scans
well - with greater  'captured' dynamic range and sharpness than either from
CN films or color that has been either 'desaturated' or channel selected for
B&W conversion.

Karl,

That applies to Silver B&W being used in a wet darkroom, but does it apply
to C41 B&W being scanned for digital printing?  The dynamic range
(tolerance) of color film is great, and can be pretty effective if you
stretch the contrast in digital processing.  I do like the quality of the
contrast of my C-41 B&W scanned and manipulated digitally.  If you print the
unmodified scanned image, it is indeed very flat.
