Photography Idea

This would require an installation.

Go to some public place, like a concert hall, but just outside it (the lobby, say). Set up a series of strongly-colored flash bulbs overhead.

After a performance (or just before), when the lobby is crowded, trigger the flashes and take a picture, from above. ...The point would be to catch the crowd unawares, in stark colors, in an interesting room.

If you're feeling particularly bold, just before taking the picture, shout at the top of your lungs so that most people will be looking at the camera.

Idea inspired by this shot.
