Undine Falls, Yellowstone National Park

Undine Falls is one of many beautiful waterfalls in Yellowstone National Park. To create the motion blur, I selected a time of the day when the falls and gorge would be evenly lit (mid day with cloud cover) and used a 6-stop neutral density filter and ISO 50 to reduce my shutter speed. A casual photographer can be seen at the top of the falls, giving scale to the scene.
