Digital BW, The Print

You are absolutely correct.  However, once you exceed the ability of the
printer and inks to reproduce those, they must compress when you print.

Just as the Zone System sought to bring exposure/film/development into the
gamut that B&W paper could reproduce with its 128 shades of gray plus black
and white.

==Hello Tom:
==
==The number of shades of gray in 8-bit is 2 to the 8th power 
==(hence  the
==256 shades of gray.)
==Multiply that binary to the 16th power and see how many more 
==shades of gray that you end up with.  It's thousands.
==Would you rather have thousands of shades of gray or 256 
==shades to work with in your b&w prints?
==If you do really make big changes to your files, and you 
==squeeze CS for all that it's worth (something that I'm still 
==certainly trying to figure out how to do), you'll find that 
==you have lots more latitude in your shadow detail than you 
==could ever possibly hope to achieve in 8 bit.
