Rather, underexposure increases noise. Your shots are slightly
underexposed.
Overexposing in order to reduce noise, will still require even longer
speeds, thus more ISO!
Do some testing. I think you'll find that similar subjects with a
+0.3-0.7EV exposure gain will net better results and not cost you
terribly on exposure time. Remember, when you're working RAW, you
want to get your exposure as close to the saturation limit as
possible without losing details in the highlight areas that are
important. That gives the best data to render shadow values smoothly.
But I frequently have to use Neat Image to try to restore
photographs made
at ISO 3200.
I would like not to have to.
I almost never even use the noise reduction in Camera Raw other than
at its default settings, even with ISO 3200, and I don't feel that my
prints are unacceptably noisy for professional presentation prints.
I still want lower noice from the next generation of Petntax DSLR's
- which
was what we were originally discussing.
Lower noise is nearly always a good thing, just like less grain. Not
always, but nearly always.
