Hi, Bob.  I didn't understand what you meant in your bracketing comment. 
  Please explain more.

Here's a nice overview of dynamic range with respect to both exposure 
latitude and density.  Not mentioned, however, is the fact that digital 
sensors have a linear response to changing light intensity whereas film 
has a non-linear response.  The exposure latitude of modern digital 
sensors is somewhere between slide and negative films.
