The lesson is a nice complement to yesterday's photography post. Destin from Smarter Every Day produced a great rolling shutter explainer. Those weird motion-based video artifacts that your camera phone captures? Rolling shutter (not the "wagon-wheel" stroboscopic effect).
Destin's explanation benefits from his intentions and Phantom high-speed camera. And some great work in post-production. Next time I fly, I will book my tickets on "Smarter Every Day" airlines!
