Thanks for posting that link! Great stuff. My personal favorite might be #3, of the Indonesian volcano trek at sunrise. But there are so many to choose from I well might have a different favorite later today ...
Photo #8 of Igazu Falls well illustrates that "scenic" photos often can be well (best?) done with longer focal length lenses. The cluster of people illustrates very well the size and scale of the scene.
All photos benefit from caption material telling the what, who, where, when and how (and maybe why) of the story -- stuff that is not inherently in the picture. I also particularly like the human element in many of these shots -- it almost invariably adds interest, scale and context.
Enjoy!
