Clouds are one of my absolute favorite subject and I have been photographing clouds for quite a few years by now. I even published a very successful, upscale coffee table art book - simply titled "Clouds" - featuring more than 100 of my best cloud images.

This photo simply LIVES of the beautiful cloud, glowing in an iridescent pink-purplish hue in the dark night sky by reflecting the first light of the rising sun which is still far below the horizon. The cloud looks almost like a UFO, hovering over the trees and the valley.
