I stood on a traffic island in the middle of Park Avenue for a half hour, waiting to juxtapose the silhouettes of people crossing the street against the flow of nighttime traffic. The quality of light was different on each side of the street – the traffic heading away from me was a mass of red taillights pm a dark street, while the oncoming traffic created a golden glow on the pavement. Given such a contrast in exposure, I had only one place for silhouetted pedestrians – the oncoming traffic side. I used a shutter speed of 1/15th of a second, fast enough to freeze the cars both coming and going, but slow enough to blur the silhouetted pedestrians who eventually walked into my frame. They seem so vulnerable out there in that sea of traffic, at least from my vantage point. And that is the point I was trying to make with this image.
