Everytime I edit past a certain point of saturation/clarity/vibrance in my RAW adjustments...the picture starts to get kind of grainy. This is across the board throughout all ISO's, etc, BUT it will take a lot more editing of an ISO 100 pic to turn it grainy, than an ISO 1600 pic, obviously. I see lots of pictures all the time that are obviously heavily edited, with out of this world saturation, but with less noise than I have. Am I doing something wrong in my editing that I'm getting this grain, or is it something in my cameras settings, or do some people use a noise reducing program? Like I said, I shoot in RAW, and edit photos in Photoshop RAW editor, and I use Adobe RGB as my default camera setting, if that helps at all.
