I shot Tinsley Viaduct on the 24th of March at 6am. Daylight was starting to break through. The image was achieved balancing the long exposure between the natural light and the street lighting.
This was the fourth image in my Architectural Challenge Series, suggested by photographer David Charlesworth.
The exposure was extremely slow which mean't that planning was required regarding position to avoid vibration but, allowing enough passing traffic to achieve the look of a busy road. Using 73 mm of focal length, to introduce the curvature of the viaduct from the extreme lower left corner of the frame, I wanted to exaggerate the amount of curvature of the viaduct, with three curves of the bridge showing which normally appear to be one long gentle sweep. It was a very dull, frosty morning creating a scene of grey which worked well to amplify the coldness of the steel. To keep the feel of the scene, I very slightly desaturated the yellow of the sodium lights as they were just a little too warm and distracting against the rest of the image. That mean't taking any reflection from the lights to a similar cool temperature.
