Last from Bryce Canyon, posted in part because of my recent reading of this article on Luminous Landscape. I was obviously at that point later in the day where the shadows were overtaking the valley. I did some adjusting afterward, otherwise the lower portion of this picture was completely lost in one big shadow.
Picture taken with Canon 60D, EF-S 17-85mm lens @ 17mm, 1/50 sec shutter, f/16, ISO 100
