Thanks! Very helpful indeed. DPP's Help really doesn't do that program justice.


Actually it's a 1DsIII capture (24-105 @ 28mm, 1/60 @ f/6.3 ISO 1600) inside B&H yesterday. Correct me if I'm wrong but I think that uses a Digic III (or maybe two of them?) at 14 bits/channel. In any case I understand now what the gray areas are for - almost.


The "almost" is this: your screen grab shows the wider DR of the 40D added (only) at the low end. Is that a "real" reflection of where the added DR is (from a 14-bit vs a 12-bit sensor)? So the 40D should be better than the 5D at capturing noise-free detail in the shadows but not any better at holding HLs?
