Please don't get me wrong, but that's just one of stereotypes in photography (that you get better picture if you shoot raw). Shooting raw can only help somewhat with dynamic range, sharpness, white balance. It can't help with more important aspects of photography - composition, focusing, lighting. Once upon a time I was obsessed with LightRoom. I only shot raw and put everything under LightRoom processing. Once for a portrait shoot I changed to RAW+JPEG and after processing compared my output files to the OOC JPEGs. I was surprised to see that my post processed files mostly resembled the camera JPEGs. I was unnecessarily spending time in LightRoom.
Please note, I am not saying LightRoom is useless. I am also not saying shooting raw has no benefits. What I am pointing out is that if you are able to set the camera properly, OOC JPEGs are pretty darn close to processed raw files. On board processors in the camera are almost as powerful these days as a full scale computer a few years ago. Due to increased processing capabilities, cameras are able to produce much much better JPEGs these days.
When I apply the "Auto correct" features in Adobe CS5 on photos taken by my D3, I only notice two minor effects. The Adobe color is slightly on the colder side (low temperature) and tone is somewhat contrasty. Even that may be due to the fact that I keep all pictures controls in the camera on "Normal". My conclusion is that the onboard processor in the camera and the algorithm applied by the onboard software produces nearly same results. See all this, now I only shoot raw when the lighting condition is challenging or the photos are more valuable to me, or when I am sure I want to put them through Adobe CS.
