Until you use it (with the right setting), you can't understand what this program is capable of doing.

It uses the Noise Ninja noise reduction engine, which I've used. I understand perfectly well what you're talking about but even as good as Photo (Noise) Ninja might be at handling noise, it's never as good as starting with a properly exposed and noise-free file. The only time a better noise reduction strategy is the correct answer to give somebody who's got a problem with creating noisy images is when the exposure is optimized to begin with and the raw files produced by the camera still include unacceptable amounts of noise.

Your information regarding Photo Ninja is incorrect in at least one important detail.  The latest version of Photo Ninja (v1.2) uses Noise Ninja 4, which is not available as a stand alone program.  Prior versions of Noise Ninja were stand alone, and you probably used one of them in the past.  NN4 is a quantum leap better than NN3, so if you have not tested PN 1.2, then you have no idea how effective its NR can be.  I am confident that the image in question in this thread would be child's play for it.  However, the best NR that I have seen is the Prime NR engine in DxO 9.  Unfortunately, as a raw convertor, DxO is inferior to Photo Ninja in almost every other way. I bought DxO 9 to have available for very high ISO images with extremely heavy noise.  For everything else, I use Photo Ninja and get better results.

I do agree with your point about proper exposure being the best way to minimize noise, but stuff happens, and even the best of us sometimes underexpose.  In those instances, it is important to have the best NR tools and to know how to use them properly.
