On a fall evening I ventured to a location above Clear Creek Canyon just prior to sunset. As I watched the sunset over the Rocky Mountains I started photographing the traffic heading through the canyon on a full moon evening. As the traffic made its way through the canyon below the light from the moon illuminated the landscape as the clouds moved through the evening dusk. With a 30 second exposure I was able to capture the movement of the clouds and start to also include in the image the stars as the day ended.
