Digital BW, The Print

I have been meaning to go back to the HDR issue ever since Paul Roark
highlighted the feature in CS2.  But capturing dynamic range and having an
image that will withstand editing curves etc are I believe different issues.
The assumption I was making with the scanner question at hand was that there
was no change to the dynamic range of the scanner.
