A tourist in your world

The camera makes everyone a tourist in other people's reality, and eventually in one's own.
           -- Susan Sontag

Interesting.
I think she means this is a bad thing. But I don't think so.

Be passersby.
Or:
Be a tourist in your own reality. 

... I think those say just the same.

I've always loved photographing, and I suspect that one of the effects of it is just that it makes you an observer instead of a participant. Again, most people would feel this is bad, but this is just the ego and the dream protecting itself. You stay trapped in the dream so long as you're participating in the drama. When you start observing instead, you're on the way out.
