I have always been intrigued with the Walnut Street Bridge in Chattanooga, TN. Built in 1890, it was apparently the first non-military highway bridge across the Tennessee River. On a daily and nightly basis, it is now enjoyed as a walking bridge by thousands of Chattanooga natives and visitors. This photo was “shot with flash/speedlight” off camera with a red gel which turned the white railings red. My camera was set for a slow shutter speed; I placed a red gel on the flash and as the shutter remained open, I pressed the flash “test” button firing the flash multiple times as I walked along the rail. Although I also shot the scene with both a purple and blue gel, I liked the way it looked with the red gel best.
