This is a shot of the Mackinac Bridge which connects the lower peninsula of Michigan to the upper peninsula. The bridge is the 3rd largest suspension bridge in the world and the entire bridge is almost 5 miles long. This year is the 50th anniversary of the completion of the bridge.
This particular shot was taken on a late summer evening. I set my tripod up and aimed the camera at the bridge. I had a 45-150mm zoom lens (90-300 35mm equivalent) on the camera and I set the exposure for 60 seconds. During the exposure I counted to 10 and then zoomed out just a bit, waited another 10 counts and zoomed out a bit more until the timer closed the shutter. The water wasn't calm that night, so I didn't get nice reflections off of the water, but to me, the zoom effect makes the bridge almost look like fireworks bursting in the sky. Somehow I think it's appropriate for the 50th anniversary of the completion of the bridge.
