[Leica] Re: the dynamic range of digital

[drodgers at casefarms.com (David Rodgers)]

Interesting but the Luminous article has a very
oddly-colored-not-quite-normal-looking-blue-if-you-can-call-it-that-sky
which makes me immediately question their authority on correct exposure.


Doug's images, OTOH, all look pretty right-on colorwise to me. So while
I don't know who or what to believe, Doug has an edge in my book. 

This digital stuff is a challenge. I've been shooting film for 30-years
and darn it if I wasn't just beginning to get that stuff figured out!

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....
