I prefer to shoot waterfalls on overcast days, but when the sun is blaring I try to make the most of it. If you go to Rainbow Falls in the morning on a sunny day, guess what you'll see?? I spent more time shooting video than I did stills. The spray was too bad to get to the rocks below the waterfall, but we went down to the side to shoot while most of Kevin's group headed up to the top of the falls.
