For this shot I wanted to try long exposure settings. Most important for this kind of set – up is to use a tripod. In my case I was also using a remote trigger to steady a camera movement. This was an important thing to do because I was photographing from a highway bridge – not an ideal place for steady framing. An interesting thing happened later. After I post – produced an image and uploaded it on the internet, I realized that one of the photographers also took a photograph from the same highway bridge, aiming at the opposite side of the road. It was a pleasant experience of how small the world of photography can be.
