I think that point may have been reached with the K-5. I saw the K-7
from K20D upgrade more of technology for technologies sake. The example
of the recovered underexposed photo just blew me away. I've tried
similar things with the K20D, and failed miserably. Maybe that shot was
a special case, but what it implies for the manipulating of raw data
files to extract color and detail is astounding.

Peter, I understand all that. The question then is when the marketing
speak far outweighs the real life applicability of technology. I, for
one, know that buying highest end audiophile gear will be waste of
money on me. The same would probably hold true if I mortgaged my life
and bought myself full complement of Leica S camera and lenses... One
has to be able to understand when the next upgrade is technology for
technology sake, which still has its right to exist, but knowing that
will allow better manipulation to get the results one wants to
paraphrase what you just wrote.

A large part of photography is mapping from one medium to another. The
more levels of data you have them more you have to manipulate to get the
results you want in the final displayed image weather that's a video
display, a print, or some kind of transparency. We used to do it with light
and chemicals.

Hmmm, so a camera with so many bits of RAW can do what then? Discern
2^so many shades, right? And the dynamic range is about when it goes
to saturation either to pure black and pure white. Ok, so tell me
then, the wise people of PDML, is there a way looking at the same
picture shot with K-7 and K-5 to tell them apart? Or better yet, how
do I /see/ that one camera has wider DR than the other and that more
BPS in RAW are more beneficial than less BPS in RAW in real life. And
how all that translates to actual print?
The only thing that comes to my mind is that wider DR and more BPS
gives me wider range of corrections in post or RAW development before
I start to see things like posterization etc. Anything beside/beyond
that?

Dynamic Range in EV has no effect on the amount of shades the K-5 can
discern, it is merely defines the maximum and minimum brightness
values which supply usable data at the same time. The ability to
discern individual shades (or more properly differences between two
shades) is solely controlled by how many bits wide the ADC system is.
The K-5 can discern 2^14 shades maximum across a 14.1 EV ( a
brightness range of 2^14.1) range according to the DxO tests. There is
no direct correspondence between the two.
