‘…there is something predatory in the act of taking a picture. To photograph people is to violate them, by seeing them as they never see themselves, by having knowledge of them that they can never have; it turns people into objects that can be symbolically possessed.’
~On Photography | Susan Sontag
I don't exactly agree with Sontag's assertion, but, since I don't have the rhetorical muscle to challenge her point, I'll have to concede it.
