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.
