Shot with Phase One XF camera and 35mm Schneider-Kreuznach lens. ISO 50, ⅓ second, f/3.5. The wide aperture keeps focus on the stump, with nearly everything else at least a little out of focus.
I also took a shot with a longer exposure and a smaller aperture, which puts more of the shot in focus and smooths out the water motion. I prefer the version above, but there’s really nothing wrong with the longer shot:
ISO 50, 2 seconds, f/10.
