It’s a GoPro, one of the biggest breakthroughs in video technology, ever. It’s a cheap, tiny, waterproof, indestructible, high definition video camera that also shoots stills.
Every two seconds it snaps another frame. One hour of real time equals one minute of video. In editing it can be sped up even more.
The GoPro’s secret is its super wide lens–the opposite of a telephoto. Being wide reduces shake and makes aiming shots much less critical. It’s great for things very close or very large–like the sky.
The whole stills-to-video process is a pain. Nothing difficult. Just lots of steps.
You see physics in action as you look at the clouds interacting with the rest of the atmosphere at this much faster pace. Everything that happens is dictated by the laws of physics. Nothing is random.
So many things look different when seen at an alternate time scale. Nature is pretty damn cool.
