It's a very difficult question. But, as we are talking of Yosemite, remind 
yourself of the dynamic range in Adams' prints of the place...and at times 
his extraodinarily subtle gradation of tone. In both the gradation of tone 
the handling of highlights B&W film can outdo present (mainstream) digital 
technology, which after all was designed to handle colour which is where the 
market demand is. We are often very fond of pointing out on the LUG you see 
different things with the two.

A B&W Digital camera would be an intersting but technicvally different 
particularly if it were to get into trying to reproduce film quality.
