There's something quite magical that can happen when a secret is no longer a secret - or is a shared secret or a common secret. By allowing those boundaries to be porous, certain forms of oppression may be lifted.

I love bells, clocks, watches - and I recall that at first photographic implements were related to techniques of cabinetmaking and the machinery of precision: cameras, in short, were clocks for seeing.

I have to admit to you, I am the person who's done probably the least analysis on the selfie, because it's a bit like pornography for me. It's this masturbatory, repetitive act that I'd rather wasn't part of my routine.

Every time you enter a space, you are on public display. Nothing is private.

Photography's relationship with pornography is as old as photography. That kind of unholy relationship is formed from the very beginning, and there's a reason why: it's thoroughly enjoyable to be that voyeuristic. Voyeurism is a very old modality, and most of the history of photography is in some way related voyeurism.

Your image is your currency in this world.

The real beauty of the time we're living through is that we can deploy our self-image in ways that can have radical social implications.
