It's very difficult to carefully compose a photograph from the passenger's seat of an automobile moving at 80 miles per hour. In this case, however, I had an idea in mind well before the moment of exposure. A rising sun had been creeping towards the horizon,signalling the coming of dawn. Meanwhile, the sky overhead featured a huge jet contrail. I noticed that the white lines on the highway echoed the diagonal thrust of that contrail. I hoped to connect thie contrail, and the air traffic it symbolized, to the road traffic flowing ahead of us. I scanned the horizon, looking for an oncoming object that would provide a focal point to accomplish this. I spotted a large sign while it was far away. It kept getting larger as we approached. I waited until that sign and the contrail merged, and released the shutter. The road traffic flowing in front of us is abstracted --we see only a silhouette of a car. We don't see a plane in the sky, either, only a symbol of air traffic. My composition expresses the point of the image itself: the flow of moving traffic on ground and in the air.
