When I'm in big cities, I try to travel by foot as much as possible. That's when I see the good shots, and if I'm lucky, I come home with one or two.

I was walking back from a dinner meeting in Las Vegas with a Canon G9 and a small Gorillapod tucked away in my jacket pocket. I felt like shooting something, but nothing caught my eye until I climbed a set of stairs for a street overpass and noticed this scene. I wanted the streaming lights of traffic driving by, but I thought they would look best in context with the Las Vegas cityscape.

I mounted the Canon G9 to the Gorillapod and wrapped its legs around the edge of the overpass so I could compose the scene. I made sure the flash was turned off and set the ISO to 80 to control noise. I then went to manual exposure mode, which is very easy to use on the G9, and played with the settings until I saw what I liked on the LCD screen. The exposure was 1.3 seconds at f-2.8. I set the self-timer to anticipate when traffic would begin to move, then pressed the shutter button.

Some of the frames didn't have the right look. But this image has a nice combination of moving lights and stationary objects. So it became my "keeper" for the night.
