I have shot a test roll of V100f about two weeks ago and was very
impressed with the results.   I was shooting rusty things in front of
blue skies, train tracks, etc and the quality was just great.  I
haven't taken my loupe to it to look at the grain, say, between v50
and v100f (I don't really care, either)- but as far as I can tell, I
don't see a non-louped visible difference between the two except
*perhaps* it appears there is stronger color saturation on the v50.  I
shoot/have shot a lot of V50 and I don't really know if I can tell the
difference.

I think, to me at least, that the benefits of 100 have more to do with
the film speed- which, then allows me to shoot macros, hand-held,
outdoors.  I drink too much coffee to do that with v50.

I'd be interested how well this film can push.  If I could get
similiar results at 200 or maybe even 320- i'd be a real excited kid.
Then again, I could just use Provia 100F and have a greater success
rate minus the pwetty colors.
