Well then it's no longer representative of ISO1600. If you increased exposure by a stop then that's ISO3200, actually even worse because the process of raising exposure generates more noise than shooting it correctly in camera at the higher ISO.
Originally posted by Zen C Is LR a decent program in terms of noise reduction? I hear that Aperture is better? Any experience with that?
I use Aperture and love it, but it absolutely sucks for noise reduction. For noise reduction I have Nik's define and Topaz Denoise, both are pluggins for Aperture. Lightroo comes with excellent noise reduction built in, that's one of 3 major advantages LR has over Aperture, Aperture though has a couple of it's own over Lightroom.
