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.
@mattblaze@federate.social that would be an interesting study series. 3 shots of the same subject at different exposure speeds.
@RDilling@infosec.exchange Indeed!
@mattblaze@federate.social I’ve always wondered what the upper limit is for the human eye. Meaning at what speed would something have to move so that we wouldn’t even register it.
@aburtch@triangletoot.party I think it’s complicated. Most of the studies I’m aware of look at our ability to perceive smooth movement from a series discrete images (like in cinema), which isn’t quite the same as our ability to perceive a fast-moving object.
