Forgot to mention with regard to the Velvia vs. Provia site, in the
region where Provia 100F shows more tonal detail (dark bridge), the
exposure value is in the range where Provia 100F has a steeper slope
and hence more contrast than Velvia. That is, Velvia is clipping into
black. The label 'high contrast' applied to a film refers to its
overall density/exposure range, and not to specific points on the
curve. The tonality of Velvia and Provia with respect to the sky, where
sharpening was applied twice, indicates grain affect on tonality.
OK, I'm done. Proper exposure, high contrast and low grain = good
tonality

It may be that Fuji recognized the different needs of scanning when
they designed Provia F. Velvia came out before scanning was common
and it was not even designed for projection. It was designed for
magazine and book reproduction using lithography. It is supposed to
have an extra black layer to get the stunning blacks that printing
needs to look good. Sort of choosing the right tools for the job.
Some wonder why buy a box wrench when pliers will do.
