This photo was taken in December 2014 with a Canon 5D MkIII and Canon EF 24-105mm f/4L IS USM.
Camera Settings: f/22.0, 0.8 seconds and ISO 50
These waterfall pictures where taken in a forest in Magoebaskloof, South Africa. I used a polarising filter to increase the shutterspeed and decrease the reflections on the water. I increased the aperture value to the maximum of f/22 and decreased the ISO to the minimum of 50 to get the longest possible shutterspeed.
A waterfall can make some of the most impressive photos if using a long exposure. Waterfalls are a very popular subject for landscape photographers. The milky water effect in all great waterfall photos is not difficult to acheive.
