My opinion, expressed in my first message in this thread, is that IF you
shoot JPEG (and most people on this list apparently don't), the two cameras
give very different results, with the Ds offering better exposure latitude.
Nothing more, nothing less.
I expect that two RAW files won't show the same difference, but that's
another topic as other topics would be the sharpness, the color rendition,
or any other performance.
I cannot check two RAW's as I no longer have the Ds at hand.

I don't think they represent a good comparison in all respects, but if you
stick to the latidude when shooting JPEG (which was my intention), why not?
What I mean is: to answer the question "does one body have more exposure
latitude than the other?", I'd have to have a RAW image taken with the
exact same lighting and exposure settings, or an un- altered in-camera
JPEG image taken with the same parameter settings, both of the same
target and taken from the same position with the same lens, to give me
confidence that I was seeing a difference characterizing the two cameras
accurately.
How can you tell that "same parameters" are same parameters? Is mid-level
sharpness the same for both models? Who knows? In my shots, the Ds was set
as default, while the D was set default on all parameters but sharpness,
which was a step lower. And those crops are NOT intended for comparing
sharpness.
RAW format exposures should be definitive.
That's beyond my intention, as I wanted to show the big difference when
shooting JPEG, which applies to 90%+ of my shots. Maybe someone else also
shoots jpeg, even it is not in fashion.
For in-camera JPEGs, you also have to allow for possible differences
between in-camera RGB rendering and JPEG compressions settings.
Yes, and this gives ìthe difference I am interested in, since I mainly shoot
JPEG. Maybe someone else also shoots jpeg, even it is not in fashion.
For example, a Canon 10D and a Canon 300D use the same sensor and similar
capture/rendering chipset, but Canon sets the defaults for the 10D
differently form the 300D *and* what the parameter settings mean are not
1:1 mappings. I found that I could get JPEGs that looked almost identical
to the 300D on its defaults by up setting Saturation, Contrast and
Sharpening parameters, but I couldn't get the 300D JPEGs to match the
10D's using the 10D's default parameters as the 300D controls had a
coarser adjustment range. The RAW files from both cameras were
insignificantly different at the same exposure
Not surprised at all. I'd be surprised if the RAW files were significantly
different.
I expect the same with *istD and *istDS.
