Loris,

But also less grainy than a 160 ASA colour neg ? I'm not familiar
with the 400 ASA chromogenic B&W films.
It is either 160 ASA colour neg film or Polaroid 665 B&W that I
use. The last is another category.
You could be right as I'm too often thinking of the Nikon 8000's
results that I have of those films.
Still I can't put the term "noise" on it. This is from the light
parts of the film.
What are the results in the shadows when scanning a slide ? If it
is a noisy scanner then it should really be visible in the
shadows.
Is this not pure an aliasing effect, there's little difference in
"noise" between the different shades in the shadows, the darkest
part looks a bit less noisy.
