The springtime rain in the Great Smoky Mountain National Park left many of the parks waterfalls flowing at above average rates. This waterfall was actually located off the side of the road. Because of the narrow shoulder, i didn't have space to use a tripod and had to pin the lens against the ledge of the barricade to get a stable shot. I took several exposures and this was the sharpest of the lot. I was using a 500mm lens to get a close enough shot and still cropped pretty tightly on the flowing falls.
Shot with Nikon D800, Sigma 150-500mm. Edited with Photoshop CS6 and Nik SilverEfex Pro 2
