Hello,

How do you manage the B&W tonality range that exceed the scanner ability
?

You don't
Well, longer exposures help. Multi-scanning also helps. A combination of
the two, like I told you Don does in a previous message, might be best.

You can only get so far, however.

The scanner only sees the density/transparency of the film. The scene
luminance differences are compressed in the non-linear film densities.

The maximum density difference the scanner is likely to encounter in
non-graphical film is probably less than D=3.0 . It is quite well
possible to encode that in 16-bits, in fact it is very possible to
encode Density differences up to D=4.8, if only the scanner were able.

Photoshop Highlight/Shadow tool (with versions CS and CS2) may help,
post-scan. If it's available to you. Use it sparingly, just enough to
still be "plausible".

I've tested it. It is a must.
