Kind of a fun picture I think. By using a slow shutter speed, you can blur fast moving objects, in this case the rushing water of Sunwapta Falls in Jasper National Park, Canada. A conversion to black and white seemed to work well.
This was one of many impressive waterfalls we visited on our trip up north, all of which yielded many pictures. Lots of tourists were around this site though and the lighting on the morning we visited was far from ideal. Rather than battle those elements, I chose to focus on close in views of the falls.
