this film is very grainy. it is not the scanner. if it was the scanner you
would see the same grain in velvia or even fujicolor 100, but you won't.
for a good high speed film try superia 800 or nhg-ii 800 if you can stand the
idea of working with negatives.
I overexpose superia 800 at +0.7ev and get spectacular results *for an 800-asa
film*. This film has a very characteristic noise, is is visible in the shadows
and underexposed areas with a distinct almost 'digital' pattern, but wil not
show as much in midtones and hightones.
my experience with kodak films was that they are awfull for anything faster
than 200asa.
