The only thing I regret about this photo is that Flickr doesn't show the exif data that goes with it. I'd love to know what camera Ryan Dyar used, and what camera settings, to capture such fine detail, such exquisite light and color, such a perfect sense of motion in the foreground waterfall. Luckily, Dyar does include some information in his description, discussing his use of a polarizing filter to make the water more subtle.
Beyond all of the technical details, though, this is an extraordinary photo first and foremost because of its perfect composition. Notice the converging lines throughout the image, the way they pull the eye in toward the more brightly lit peaks in the background. This is the very definition of a perfectly composed photograph.
