Based on what Paul said today and previously,
it looks like there might be a sample-to-sample variation.
I have my K-7 set to +0.7 - +1.0 for most of the indoor shots.
This is when the metering is set to center-weighted ("green") setting.

It's okay to expose to keep the shadows from going completely dark, but
you usually shouldn't need plus 1 or 2. I rarely have to use plus EV with
the K7. When I do, it's usually +.3. or sometimes +.7 when the most
important part of the shot is in shadow. If you expose accurately at ISO
400, you won't get a lot of noise. The fur protesters pic I posted
yesterday is ISO 400 in program mode with no exposure compensation. The
doorway is pure black but there's no noise:

This pic is ISO 1250. I was in program mode, which picks f4 with the DA*
50-135. I went with +.7 EV because her face was shaded, and I pulled back
the highlights in conversion and burned in the hot white papers on the
table after converting:

This shot is ISO 6400, shot at the meter reading in aperture priority
mode. There's noise in the deep shadows but the main subject is relatively
noise free, and he was exposed correctly. No post work to speak of on this
one, other than a slight application of PhotoShop noise reduction:

been really surprised about the noise in the shots. My brief required me
to shoot the interior in only available light (although I did cheat and
use a little bit of flash bounced into some of the shadows some time), and
there is A LOT of noise in the dark (shadow) areas of the images. (I will
post them later but can.t log into my ftp server right now for some
reason, and I am sitting here on hold to the hosting company as I type
this!).
> So, my question is this . if I am shooting in RAW, it means that the HDR
function does not work. Noise wasn.t a problem like this with the *istD,
so I.ve never really thought about this in depth, but if I were to
deliberately overexpose by one or even 2 stops (but not too much to
completely blow out the highlights), and allow more light into the shadow
areas, would this eliminate much of the noise in the darker portions of
the pictures? Because I am shooting in RAW, it shouldn.t be that hard to
adjust the curves/levels in the RAW converter to compensate so that is no
problem, but NOISY pictures (especially for print magazines), certainly
IS!
