This is a video of me juggling on our deck. The first part is regular speed, 30 frames per second (fps); the second part is 1/8th speed, 240 fps. The 1/8th speed is what I use for slow-motion dragonfly videos. It's good to keep this in mind, because it's easy to watch the dragonfly videos and think of them as being regular speed. It should always be remembered that we're seeing the dragonflies at speeds that make a person look like a sloth.
