Groucho - do you have any before pictures for comparison?
Ahh, you want to peek behind the curtain?

Seriously, though, sure.
Since they're already loading if you're looking at this page, I'll also show the de-noised ones again. I kept the sizes similar to make it fair. These are both ISO 1600.

The noise levels in the originals weren't bad at all, IMHO, I just figured that I'd clean them up to make them that much more presentable. I usually don't bother due to the loss of fine detail, but I have been going through my old 5mp PnS pictures and trying to clean those up - many of them are big, noisy messes, and a presentation but "plasticky" picture is better than one that is shamefully noisy.
On general Spectromagic talk, here's a couple of "failed" photos that are kind of interesting.
I think this was one of my attempts at panning - didn't work, and someone else's flash going off during it gives it a really strange effect. ISO 400, F3.5, 1/8th second.
Speaking of flashes, they do look kind of interesting when you catch other people's going off... here's two... ISO 400, F6.7, 2 seconds.
