I scan slides.

Yes.  It means 12-bit output, which gives a _theoretical_ dynamic range of
4096:1, or log(4096)=3.6, for density range.  (A range of 3.4 actually
corresponds to about 2500:1.)

Unfortunately, actually achieving this with the scanner is much more difficult.
My LS-2000 is just barely able to extract most of the detail from a slide, but
it is very noisy in the shadows and tends to blow out in the highlights.
