He *did*, until quite recently; but these days digital does a better
job.  Then again dye transfer printing is excellent for color fidelity
and shadow detail, but not particularly superior for resolution, so he
doesn't need superb resolution (for 16x20 prints).

I edit in Prophoto, and render final output to sRGB because that pretty
much covers what you can print (most labs insist on it, in fact).

The old claims were that prints had about 5 stops, slides 7, and
negatives 10.  You seem to have a much higher opinion of the usable
range of negs than I've heard from others.

However, storing film correctly is much more expensive, bulkier, and
harder than storing digital correctly (controlled-humidity
low-temperature storage).

Digital archives don't do well under a regime of blind neglect, I'll
grant you that.  They *must* be actively managed, including both file
format conversions and media conversions as needed.  (Not much needed
yet; CDs are still readable on new hardware, JPEGs and TIFFs are still
readable in mainstream software, etc.  But absolutely, over 100 or 1000
years conversions will be necessary.)  However, *with* proper
management, digital archives can last *forever*.  Analog media isn't
good for very many centuries even under pretty good conditions.

For a total cost of under $3000, I store all my images on a system with
fully mirrored storage, which checks every week for any data or
meta-data block having gone bad (not just reading the blocks to see if
the disk thinks it's okay; it stores a separate checksum of its own, and
verifies that).  Disks can be replaced "hot", without even powering down
the system.  And I have three backup sets, one off-site and two in a ETS
two-hour rated fire safe.  It's not *that* hard.  (My system could
support a LOT more storage, using bigger modern disks, but the backup
sets start getting expensive; I'm not shooting commercial quantitities,
so my total backup sets including years of history are under 2TB.)

Which puts it past any film specs I'm familiar with; I don't know where
your figures are coming from.  Probably, I'm guessing, film people
define the terms and measure things differently, so they're not
comparable to to still photographer numbers.
