Where did I write that, B.D.?  Show me the post where I claimed the DMR is
the best there is.

And where did I write that?  I'm saying that it not behaving the way
Reichmann or you believe it does. Apparently to get an optimum histogram
you and Rechmann need to overexpose on the cameras you are using.  With the
DMR I have to underexpose to get the same optimum histogram.

B.D. I'm not disagreeing with Adobe or with Reichmann' optimum histogram. 
I'm disagreeing with your blanket statement that underexposing with a
digital camera gives you a 20% data loss.  That might be true on a camera
that tends toward underexposure but not true on a camera that tends toward
overexposure.

Are you even reading what I wrote?  You're arguing with things I've never
written or believe.
