[filmscanners] RE: Density vs Dynamic range - was: RE: opinions? Reviews? of Primefilm 1800 ?

Not true.  You can represent ANY density by any number of bits.  I can
represent an entire density range with two bits:

00 - at or below dMin
10 or 01 - between dMin and dMax
10 - at or below dMax

This is a completely valid encoding of density range.

I have to run now, so I'll comment on the rest of your post later.

Regards,

Austin
