I was associated with the MIT Juggling club in the early 1980,s. Doc Edgerton came to the club and asked us juggle in his lab at MIT, so he could take pictures.
He used a strobe (which he invented) that flashed continuously. I don't know how you could reproduce that.

Well lemme tell you this is like 40 years later. And the bullet thing chronometers are cheap these days 100 bucks or so. And with measurements and triggering the lights and camera from the chronometer takes about 5 bucks of electronic parts.
Not trying to take anything from Doc Edgerton but: The strobe, it only looked like it was continuous. And that is because your eyes have persistence with bright lights. Juggling is way not fast. Very easy to stop that motion. Especially nowadays man that was 40years ago. Electronics alone is way better not to mention camera technology. Some of these cameras you could bright light the jugglers and slow motion and or stop action. The equipment available then is no match for what you can get now.. The camera system in the SR71 moved film almost as fast as the plane moved.. That is pretty awesome but you aren’t buying those from amazon..my comments about the bullet picture just stated my opinion about the triggering method. Far easier to trigger on the bullet actually. Yes the chronograph is used to measure the velocity of bullets in flight. The bullet is fired between the measuring screens which are set at a known distance apart. Forget about the sound for triggering there is too much delay because most rifle rounds these days are yes supersonic lol but you still need to be able to measure the velocities if you are a marksman/handloader... just saying not hating.
