To shoot this photo, I aimed at the light trails of cars moving through an intersection. As the picture was taken at close range as compared to the aerial shot , the finished photo brims with an even greater sense of motion.  5 shots were taken at a shutter speed of 4 sec here, and then  combined using the Compositing Tool in  the “Digital Photo Professional” image processing software that comes with the camera. I observed the changes in the traffic light along with the patterns of the car movements, and took shots of the traffic at the intersection going straight ahead, turning right and turning left. I then combined the respective shots into a single photo and made the paths of the light trails denser.
