Why use in-camera sharpening/saturation?

[Canon Fan]

Well, maybe the approach depends onthe event you're shooting. If you're going to be covering an event like a tournament that will take 8+ hours, do everything you can to minimize post-processing. If you're shooting for an hour, shoot raw with no in-camera optimzations.

Or shoot film and don't even worry about post editing
