Never thought I would say this, but that is an aweful lot of noise at 12800. I have shots at 20000 that don't appear to have that much noise. I did do some NR, but wow, that is really noisy for a low ISO on this body.
well that's because he played with the curves to give that look, and that's messing with the raw. I dont see the noise an issue really, looks like good ol grain, and it would print fine, even fairly larger sizes.
