This was taken in Blackfriars, London, alongside 
The purpose of this image was to capture a long exposure of the street down the middle, turning those tiny little cars into nice, straight streaks of light that roam across the road and off into the distance, with the skyscrapers and buildings between adding a bit of perspective.
The problem, though, was the time of day and simply lack of cars coming down that specific street. While I did try, you can kind of see those streaks of light, but just not as much as I had intended. I think this was a 10 second long exposure, and I'm still very happy with the results despite the lack of actual light streaks that you'd expect from a long exposure of cars at night.
With a little Lightroom post processing, I have managed to turn the image into something salvageable, adding emotion into the image through colour, rather than the focus being movement and the chaos of a city at night. Oh well, there's always next time to capture the perfect image.
