In the world colonized by Arbus, subjects are always revealing themselves. There is no decisive moment. Arbus’s view that self-revelation is a continuous, evenly distributed process is another way of maintaining the Whitmanesque imperative: treat all moments as of equal consequence. Like Brassaï, Arbus wanted her subjects to be as fully conscious as possible, aware of the act in which they were participating. Instead of trying to coax her subjects into a natural or typical position, they are encouraged to be awkward—that is, to pose. (Thereby, the revelation of self gets identified with what is strange, odd, askew.) Standing or sitting stiffly makes them seem like images of themselves.
