75 Seconds at Watson Lake, Prescott, Arizona 2/22/2024
We’ve all seen images with blurry or almost invisible people in them because someone moved during the exposure. The longer the exposure the more distorted, blurry, and odd-looking moving things become. Long exposure photography can exploit this to give us “surreal” images of water appearing to have a solid, mirror-like finish and cause clouds to look like long, white streaks in the sky while rocks and other non-moving objects remain sharp and in focus.
Digital Photography School has a good intro to long exposure photography you might be interested in, and a search on Google will find many more articles and tutorials on the subject.
