Hehe, the picture was a little noisy on the camera (needed high iso or flash, but flash wouldn't ruined it). So the only way to make a slightly noisy picture better is to make it very noisy on purpose afterwards And then it kinda works...
I covered a wedding ceremony with my brother-in-law yesterday. I've never been so challenged for lighting, what with my D40, slow zooms, SB-600 and a high, dark ceiling. My fast lenses are all short primes, so I could only use them for a few shots.
Next time, I will rent a fast telephoto zoom and better body if I don't them yet.
