A I usually only shoot RAW with my D90, but once in a while I will shoot both RAW and JPEG just to compare. The JPEGS I get from this camera usually look over processed, colors look too saturated, etc. The RAW files I get usually have a more natural look to them. Usually I dont have to do anything to my RAW photos at all. The only exception is if there is a photo that I really like I will go into CS5 and do some sharpening, but thats basically it.
