I didn't consider shooting this waterfall in landscape orientation, so this was a spur of a moment thing. It turns out to be a very good shot. I didn't want to use Zuiko 35mm f/2.8 either, but also a pleasant surprise (It's an inexpensive lens). Lens hood on. I used OM 4T's hilight spot meter, and as you see, works like a charm. Hoya Moose's filter on quarter turn. No post-processing. Straight out of photo lab.
