[Batman] why doesn't batman camouflage his whole face?

If stealth and his secret identity is so important, shouldn't he camouflage his jaw? It would make him harder to aim at and obscure his skin tone.

People have given good practical answers here, but there’s another element to it as well: the answer Batman gave to Joker when he asked the same question-“to mock you.” 

Batman is supposed to be a terrifying force of nature to the cowardly and superstitious criminals, those who would prey on the innocent and harm the weak for their own benefit. But to those in need, the people of Gotham Bruce is trying to protect, the exposed jaw shows them that he’s not a demon or monster, but a person who wants to help and save those who need it. To Joker, someone who believes in the inherent evil of humanity, seeing this contradiction of punishing avenger and compassionate hero, a dark knight trying to save the city by fighting evil on its own terms, this is a spit in the face to everything he believes.
