Thank you very much everyone, I am glad you enjoyed it
About the crowd, when this photograph has been made (August 2010) there were about 5 other guys besides me; we shot the arch from close, and then we all moved out to shoot it from afar, and back close to keep working. I have been there again this February, and when I arrived there were about three guys; in 15-20 minutes, though, there must have been 100 people (!) shooting, walking around, running over the arch, you name it. It would have been completely impossible to shoot an image such as this...
Still, a wonderful place to visit and witnessing the sunrise there makes it worth it to endure the crowd, IMHO.
Thanks again, best
