[Leica] Re: the dynamic range of digital

[bd at bdcolenphoto.com (B. D. Colen)]

Being the digital expert you are, Doug, I would have thought that you'd know
that by under exposing a stop, you're throwing away everything at the top
end of the range - in the highlights - not the shadows - and 20% of the data
is in that top stop. But I don't use a DMR, so of course I know nothing
about digital ;-) - so don't listen to me, but do try reading this...from
the Luminous Landscape site....
