Actually, that's what I'm having a "problem" with...calling that 4k rez...
(which is what the gist of my involvement in this discussion was about,
trying to understand what it meant, and why on earth anyone would call it
that ;-).  I know what you mean by it, that the long side of the 35mm frame
is 4k...but that isn't the "language" that scanners (printers etc.) are
spoken about in, but it appears that film recorders have their own
definition of what "4k" means.

Understood, and I'd say you're probably %100 right, but that's projection,
which really doesn't allow for the most critical viewing.  Now, not that
that doesn't work perfectly for some applications, that's not in question.

I don't doubt that either, but make an 11x14 of it...

Oh, I have no doubt about that either, for *practical* use...since practical
use, to me, means happy snaps at 4x6 ;-)

And professional, and artistic...

Since I'm a B&W person (in a photographic sense at least), I will be using
film for a while.  I have found, through personal experimentation, that
scanning B&W film using a single ND filter is far far better than scanning
B&W in RGB (which is what every scanner I know does, except one) and
converting.  Same is true with B&W images from CCD cameras.  When I use a
scanning back, and a ND filter, it gives me amazing B&W images, and not as
good with I shoot using RGB and convert (sharpness etc. aside).

Regards,

Austin
