I love pictures of steel bridges and I love long exposure night-shots - this photo has both. According to the photographer, this was taken with a Canon 40D & Tamron 17-50mm at f/32 over a 70 second exposure. To get a crisp night-shot like this, you first need a good tripod. Once you have that setup properly, set your shooting mode to timer to avoid any movement in the camera as the shutter opens and closes.
