There was a live band at the weekly blues dance last night. For various reasons
I decided not to shoot with flash, but just go with available light. The
musicians would nod their heads fast enough that I kept having to boost the ISO
to get a fast enough shutter speed, and ended up shooting at ISO 20,00. The
thing that impresses me the most isn't the lack of noise, but the quality of
the noise.
With my K20 the noise was mostly blue, which just looked bad. With the K-5
even when the noise is really obvious, it looks almost like one of those
paintings that are done with making little dots. Stippling? Impressionistic?
Pointillism. You're not quite there, as you can see from:
http://en.wikipedia.org/wiki/Pointillism You are, indeed, closer to
stippling.
One of the best-known examples:

Nearest I've seen photographically were slides from Agfa ASA1000.
Mind you, for ISO 20,000, the noise is pretty freaking amazing. The thing that
I notice more than the noise in some shots is the dynamic range, when there are
bright lights in the background, posterization abounds. In some cases I get
this weird halo effect around the people, I suspect that it might have
something to do with the out of focus blur bringing the bright lights in the
background out of clipping and into color.
