FWIW…if you look at a pic and see the pp first, then the image, then there is far too much pp being used. It never hurts to scale it down. I’ve had people sit next to me and watch me while I worked on an image, and they still had trouble seeing the difference between the original and the final version. As someone said, ‘It’s like the original only better’.
Also, if your skin tones are whacky in camera, then that won’t change unless you go crazy with the RAWs (I also shoot Manual in RAW and work in PS CS5). Try to get your wb right straight off the bat. In cases of mixed lighting,try wb on auto. Hope this helps.
