Upper Waterfall, Johnston Canyon
At the very end of Johnston Canyon is a famous waterfall that apparently has only the rather mundane name of "Upper Waterfall". When I got there I knew I would want to try to capture the falls, and the lacy way the water cascaded over the rocks meant I would want a long exposure to "soften" the water. Only one problem: I was on a rickety metal catwalk with other tourists and photographers milling about! I waited patiently until the crowds cleared enough to awkwardly set up my tripod, then took a lot of shots, most of which were ruined by vibrations caused by people walking around. Finally, I got one that worked!
You can see the arc of a faint rainbow near the bottom of the image, caused by sun passing through light spray from the waterfall.
