Ahhh, I thought you used Photomatix. I could tell on this photo once I enlarged (along the bottom edge). I will say I am quite envious of your camera, that's the one I've been scoping out too. Very nice gear which should allow some absolutely stunning images when you go to your crazy places. :P
Neat Image is another good program for reducing noise too.
