Are you sure the camera doesn't do that? Properly done bracketing and
combining should yield a HDR image.

Actually that the amount of noise in a given pixel of a given image is
random, and thus will tend to decrease when values are averaged. See

Yes, but not the same as HDR.

Agreed.

Metaphorically speaking, or is that retorically?

Your camera runs on steam and gears?

> It's not averaging,

Nikon does (spatial) averaging, at least on longer exposures, even
with it's RAW! Astro-guys are regularly bitching and moaning,
as that blurring is of course less than perfect for fainter stars.

Google for Nikon and "Mode 3" ...

And yes, it is averaging.

It seems to me you're relatively new to the group, so welcome. Don't
mind rude jerks like Floyd L. Davidson (who has no sense of humor and
a major stick up his ass). Many of them are good resources, so take
what you can and ignore the rest.

Nah, the new Pentax looks nice though, the cost to replace all my glass is
more than I need to spend although I could be swayed when I retire with all
that cash to burn, what about you? The D3's do look very nice!
