I promise, I did a search for a similar thread and didn't see anything. So if there is one then you will just have to hurt me.
Took my lovely queen to a play on Sat. I have never shot in that kind of environment with a digital. Used ISO 1600 which I have only played with in the past. No flash used. Some pp done on brightness and contrast. Used the NR feature in DPP.
Didn't turn our bad at all.
What do you have?
