I asked the NTF community for some help fixing this underexposed / "noisy" photo and they responded in their usual, generous fashion by offering suggestions and some RT versions listed here. The first photo is the original "out of camera" shot that needed some serious PS work. If you're interested, I've listed the original thread: http://forums.dpreview.com/forums/read.asp?forum=1007&message=5371593
Thanks again for the help :-)
