What talented photographers do cannot of course be characterized either as simply predatory or as simply, and essentially, benevolent. Photography is the paradigm of an inherently equivocal connection between self and world—its version of the ideology of realism sometimes dictating an effacement of the self in relation to the world, sometimes authorizing an aggressive relation to the world which celebrates the self. One side or the other of the connection is always being rediscovered and championed.

— Susan Sontag, On Photography, 1977
