That's my next step. Like I said, the low NR pics were noticably sharper. I have to admit when I first starting looking at some of my photos with the D7k I wasn't real impressed. The default settings are not impressive (over exposed, flat colors, and soft). Now I have started changing the settings and I'm becoming happy with my new camera. For Jpegs I've found: use Landscape mode and increase sharpness to 5 or 6 (4 is default), reduce NR, and decrease exposure by 1/3 or 2/3.
