This was taken a few minutes before a winter sunset from the wheel of my car, stopped at a red light on Market Street. One of my best Arch shots in a while, IMHO. The air was so clear and the light so intense that the sunshine caromed off the stainless steel and made the pavement shine. The pattern of the building at the left, which has a polished granite and glass facade, is inverted by the shadow of a larger building off camera to the right. The picture was unplanned. Be ready, keep your eyes open.
