It's not that simple!
What comes out of the camera differs from camera to camera & remember you can tailor your camera to your own requirements in the camera's menu.
For example:The Leica M9 has next to nothing in the in-camera processing, so the RAW files need post production.
The more the camera (you use) is aimed at the professional market, the less in-camera processing goes on, that's why we shoot in RAW / DNG.
Amateur cameras are set up so you can use the resultant jpegs direct from the camera.
I shoot with average setting dialed into the in-camera menu, meaning I add some post production values once in the post production software, usually a little colour saturation, shadow & black, some Recovery, some clarity & vibrance.
These I have set up as a default in the CS3 / LR2 software so it's done immediately. I add a little where required, possibly vignette, maybe b&w, etc etc, in short, not too much of a deviation from the original image.
Occasionally I will work on an image if it's worth of it – such as the opening image on my site (which needs some serious updating! HERE
