Digital BW, The Print

Sorry but I’m going to make some simple statement here – beyond that you’ll have to ask others.  The 17 stops are handled by the film and the way I process it prior it to going anywhere near a scanner.  The scanner simply deals with scanning of a piece of film that has everything from clear film base through to dense areas of highlights.  No real difference from anyone else’s negative film.  It’s not a technical question - TIFF encoding doesn’t enter into it any more that it does for anyone else who scans their film.

.... and you really capture 17 stops of range in 16 bits?
How do you technically achieve that? Isn't the TIFF encoding
a linear value? In which case, I wouldn't expect more than
16 stops (at best) to be possible in the TIFF file, right?
