This is a reproduction of the answer I gave you on Jan 25th for this pic:

Noise depends on your sensor size and quality of the processor software within your camera and of course, ISO settings. As a rule of thumb, the higher the ISO the more noise you get.
With my old Nikon Coolpix 995, noise was noticeable at 400. With my Canon 10D (this picture), it was at 800. But with my new 1D MkII, it's at 1600 that you can notice it.
I do not use NeatImage because I did not have to yet. But I can see from some of the postings on TN that it's a great tool. I will consider using it for 800+ ISO.
This picture was taken at 400 with no postProcessing regarding noise.
Hope this help.

Thanks a lot for your comments Livio.
It's always a pleasure to read your comments and to look at your own pictures.
