Depends in my view on the type of camera on a Fuji 4700 I found the camera settings gave a more pleasing image when printed out comapared to Photoshop postwork.. I have not found the need to do anything on an SLR apart from reducing noise on occasion or add a little bit more saturation.. Some of these in camera settings are handy in adverse conditions maybe better to add some blue to a scene that is a tad on the yellow side etc.. Like all things experimant and see what works best for you
