Glide, by Grahame Taylor:
In all my slow-motion work so far, I’ve used a static camera to capture a high-speed event. But, I wondered, what would happen if the camera was the fast-moving object? Use a 210fps camera at 35mph, and on playback at 30fps it’ll seem to the observer that they’re moving at walking pace- but everything observed will be operating at 1/7th speed.
