In this example, my objective was to juxtapose the huge waterfall with its spectacular surroundings. In doing so at 80mm, the waterfall becomes small, while the canyon that surrounds it becomes huge. Since Yellowstone’s glaciers melted 15,000 years ago, the Yellowstone River has carved out its own Grand Canyon – slicing a thousand feet into rock softened by ancient thermal fields. This accounts for the unique coloration and texture of the canyon walls, which I feature in this image. The effect is magical, and this reasonably wide view tells its story well.
