A large jet begins its descent into the Phoenix Sky Harbor Airport, about thirty away from my camera position. I caught its long diagonal contrail as it echoes a cluster of diagonal clouds gathered about a setting sun. By spot metering on the setting sun, I underexpose this image, abstracting a cluttered horizon lined with what would be distracting buildings and trees. I thereby simplify the image, and allow the rich colors of day’s end to tell the story here.
