Where I had a problem was with the "film has a dynamic range not
excceding 1000:1", and that does not agree with the publshed
information.

Who, besides *you*, said that?

You: "Film can't match a typical 12-bit digital camera, though it's a good
match for 10-bit cameras." I might agree were you to add "under typical
usage conditions".

So *I* said nothing that equates to "not exceding
1000:1", which is something *you* made up. A
manufactured quote...

"A good match for 10-bit cameras" means that the two are
close, and the film maybe even wins.

And what does "under typical conditions" have to do with
it that was *not* inferred already? Even under unusual
conditions film just doesn't have as much dynamic range
as the typical top of the line DSLRs today (Canon 1DsIII
and Nikon D3).

What you suggested is to compare to a film that was
discontinued a decade ago, and indeed one which
*doesn't* even get your fabricated 1000:1 ratio!

Here's another URL to review. Note the age of this
webpage, and the fact that DSLR's today are running more
than 2 fstops _better_ than the one shown.
