Thanks all for your replies,
 
Norman examples are interesting, and I'll definitely have to make some
experiments with other films/scan settings. Definitely enhancing contrast
makes "grain" (or whatever artifact this may be) stand out, but I have other
scans from the same film (shot and developed at the same time) which can
stand the same amount of manipulations in PS without problems.
I'll post again when I have more consistent samples to report.

Norman writes in his report that at 300 ppi the 2450 produces
grain aliasing due to the stepping of the scanner that is then 8
times rougher. Less obvious with 600 and 1200 ppi. A grainy
colour negative as the subject. It is hard to predict when it
occurs and what the causes are.

So the grain doesn't have to be resolved to get the grain
aliasing effect.

I think it would be wise for Alessandro to check other
resolutions in scanning of the same negative and if that doesn't
help to change the film type he uses to see whether that helps.
The stepping of the 3200 could be different to the 2450 so the
2450 tests have to be translated.
