The colors can be pretty vivid to begin with. In some cases I tone them down or shift them towards a more accurate color. I shoot in RAW, so the contrast straight out of the camera isn't all that impressive (that's what Curves is for). A RAW file has been compared to a film negative by some, but in addition allows you to compensate for white balance and slight exposure errors. It allows you a bit more creative freedom and edit ability than your standard JPEG.
