RE: filmscanners: Polaroid 4000 vs. Nikon L4000

Rather get involved with the "specmanship" issues. I suggest you try each.
Polaroid offers a 30 day "good as gold" guarantee so if your are
dissatisfied for ANY reason you can return it to your dealer for a full
refund, excluding any shipping costs.

My impression is that neither is as good as true 16-bit scanning 
would be, that each scanner's software necessarily puts its lower 
high-bit scan in a two-byte/16-bit wrapper for the computer, 
hopefully without doing any harm by supplying the missing bits. I 
don't see how that could be as good as actually having used all 16 
bits in the measurement of the colors. But I don't know of a true 
16-bit option, and I'm just getting started with the SS4000.
