Apollo 11 Moon Shot, Cape Kennedy, Florida by Garry Winogrand.
Being watched watching them watching the launch.
SFMOMA is currently hosting an exhibition of Winogrand’s work, including this. I popped in at lunchtime and it turned out to be remarkably dense (small prints will do that, I suppose) and pretty busy.
To make the most of it, I think I’m going to have to go back. The exhibition runs until 2 June, 2013.
