Very nice, Gigi.
The highest I went was ISO 6400, and the results were OK, although I had to use NR. Those were shots of birds, with some crop enlargement and a bit tricky shadows.
What is much more important to me is that up to and including ISO 1600, I do not see any noise, and only at ISO 3200 I start to see it, but NR is still at my discretion, i.e., usually not really required.
wedding photography is another kind of beast, and when you print the photos on paper, part of the grain is lost, this is why I donīt use the NR at all.
