Hi, I know it has been done before. But this morning I was shooting my cat at ISO 51200 in an almost dark bedroom at 6:30 a.m. today. Canon 5D3, Canon EF 50 F/1.4 @ F/1.6, 1/40 sec. While a small amount of ambiental light fingered into the room I manually focussed at the animals ears which I saw better than it's eyes, therefore the face is slightly out of focus. Photograph above: no NR applied. Photograph below: NR value in both Luminance Noise & Chromniance Noise: 14 out of 20 in Canon's free software Digital Photo Professional. This goes way beyond my wildest enthusiast amateur dreams! Watch it in full mode, although due to reduction in post for webupload the difference is less obvious. But the pic without NR looks as grainy as back in the filmdays...But that's quite awesome at these ISOs! 8)
