Captured on a short hike with a small mirrorless camera, 35mm lens, lightweight tripod, and enough neutral density for a roughly 30 second exposure.
Flowing water is a subject that lends itself to motion studies that reveal what our unaided eye can't see, controlled by exposure time. At 1/3000 sec, every drop of water freezes in place. At 30 seconds, we see smooth, cloud-like structures that obscure individual perturbations. Only at around 1/30 sec does the camera see what we do.
