If you'll read the brief article at this webpage carefully, you'll 
see that it's in agreement with what Austin has been saying.

The two pictures of the buildings are a perfect illustration of 
images with identical "density range" (i.e., they both go from full 
white to full black), but with different "dynamic ranges".

Also, don't be fooled (as I was, at first) by the phrase, "the 
dynamic range does not automatically correlate to the number of tones 
reproduced".  That phrase isn't saying that Austin's understanding 
of "dynamic range" is wrong.  It's saying that Austin' understanding 
is right, but that an image system's dynamic range is merely 
potential, and that it may still produce images that don't make full 
use of its dynamic range.  -- Herb
