For this wide waterfall shot we went for a vertical, to include the full height of this picturesque scene. Using a wide-angle focal length of 24mm, I focused on the most interesting parts of the waterfall rather than getting the whole scene. Shooting from a high vantage point and aiming the camera down, I was able to capture the swirls at the bottom, where the water crashes over the rocks, for some interesting shapes. It was dark inside the forest so a long exposure captured the movement. We found 0.3 sec was the optimum shutter speed for water blur, but with rocks still visible – any slower and they disappeared.
