Time to add a little more - this time HIGH ISO. This shot from my gallery is a photograph of a print made in the 1979's by me. It is shot with the D300 at ISO 3200 - I have not used any noise reduction on it because all I can say is .... "What noise?"

The sequence of five are similar shots of old prints ISO is either 1600 or 3200 - see exif - none of them had any noise reduction applied.
Well done Nikon is all I can say.
