I keep reading about my camera's excellent noise reduction and color capabilities in jpeg mode, which leads me to four questions: 1. Shouldn't I just always be shooting in RAW? 2. If not, is it reasonable to only shoot in jpeg mode when I'm not trying to be artsy and have the camera set to P mode? 3. Can someone explain to this novice what's so special about this jpeg in-camera processing? 4. I could be wrong, but I thought I read that this stuff only works when not in burst mode. Is that true? Thanks!
