From Me to You to Me again.

I surround me with you, the camera is the eye and you all look at the image of the camera. The eye comes close to me and then I turn it close to you, so you look at your image.
I give the camera to you and the eye changed minds, so you look at your image trough the camera.

The camera has a powerful eye that makes you notice, also when you have the ability to use the camera.

 

On the one hand, the system is “open”: if I turn on myself I make myself vulnerable, make myself available to a viewer.
On the other hand, the system is “closed”: if I both start and end the action, I’m circling myself up in myself, I’ve turned myself into a self-enclosed object: The viewer is left outside, the viewer is put in a position of a voyeur.
