Around 7PM the clouds began to dissipate and color returned to the western sky. By 8PM the lingering clouds were thinning out even more and lingering over the southern sky where I hoped they might pick up some of the reflected light from the setting sun. Luck was with me as the sky lit up and the while it was still bright enough to record nice detail in the city buildings.
The final image is over six feet wide and can go much larger in a print. The color of the sky and city were not altered. A very soft haze in the city absorbed color from the sky and carried it into the bottom half of the photo. The full drama of the color and clouds didn't last very long, maybe five minutes. I had enough time to capture two passes with the camera before the scene began dulling down.
