The suspended moment.

People asleep on trains, buses, in parks, at events, in waiting rooms. Sleep in public is a moment of total vulnerability. It's also surprisingly funny.

How to shoot it: Trains, buses, parks, waiting rooms and events, anywhere people drop off in public. Shoot quietly and quickly, and draw a clear line, there is comedy in a commuter slumped at an odd angle, but never photograph the homeless or vulnerable for a laugh. A longer lens keeps your distance. Look for the surreal pose and its context, and leave if anyone wakes and objects.

The output: A series that's tender and slightly comic simultaneously.
