Kids are often told to sit still.
Photographers need to sit still, too.
Try staying in one place for an hour (an hour!).
If you're in NYC:
• The atrium at the old IBM building
• A bench in Battery Park
• Lobby of a museum
• Carousel in Central Park or Prospect Park
• Railing in the entryway for Toys-R-Us in Times Square
• Or ?
Turn off your cell and Blackberry.
You'll be surprised at what you see, and would have missed, had you walked through the space.
