Latitude

Any camera can have noise at low ISO sensitivities which will come out in low light conditions or if a shot's underexposed. What's important is how much flexibility you've got to improve the exposure without bringing out the noise. This isn't an egregiously dark shot, but you can see how bringing up the exposure starts to show a little color noise. I could probably have tweaked it a bit more with some time.

(1/80 sec, f2.0, ISO 80, evaluative metering, AWB, 4 inches away, 24mm; inset is the retouched shot.)
