Actually, if it's not captured with high speed video, then it is captured with a very brief flash from a custom strobe. The camera is usually tripped by an audio slave that fires when it hears the gun fire. The flash is the effective shutter speed. If the flash's duration is 1/16000 of a second, the camera could be set to any shutter speed as long as it is not faster than 1/16000 of a second. I'm not sure of the exact figure for the strobes to stop a bullet in flight but hopefully I explained it clear enough without confusing myself :lol: I'm not saying it can't be done with ordinary gear; just saying the odds are against it.
