[filmscanners] RE: Noise in Polaroid SS 4000 scans

["" <Harry@vdKrogt.nl>]

OK, I scanned some negatives Fuji Super G 100 I had. The scans were more
clear, no comparison with the Fuji NPS, I think. So it must be the
combination of the Film and development by the lab or the way the
scanner reacts to the grain in the film, or both. In both cases I must
look for another 160 ASA film (and I will have other NPS 160 developped
by other labs, and see if that makes a difference).

Thanks for the answers,

Harry

Hi Harry,

to rule out the possibility that the problem is the film you can shoot a
test roll of a good 100ASA film: Kodak Supra, Fuji Reala or Superia
should all be so far from the grain (assuming it's grain) you see that
it would be immediately clear whether the problem is in the film or in
the scanner. In the meantime, a major difference between noise and grain
is that noise is
random: so if you use the multiple pass option of Vuescan noise should
be greatly reduced, whereas grain would remain substantially unchanged.
