I’m confused with a strobe with a short flash duration I can shoot within my camera sync range? I don’t need to go to 1/2000 to freeze motion?

Yes you use the flash sync speed which is actually 1/250 or 1/200th of a second and use the flash duration rather than the sync speed to stop motion. The paul c buff einstein is popular for this because its digital

Hello Keano – Sorry for the very late reply! You still need to shoot at your camera’s fastest synch speed (or slower). In a controlled environment that is lit by electronic flash, you would not use 1/2000 as a camera shutter speed to freeze motion. You do it by using strobes with a short flash duration (the actual time the flash stays lit). Imagine you are shooting in a black room with no light whatsoever. What difference would the shutter speed make? None. You could set the camera on bulb or the highest sync speed and get the same results with electronic flash. Hope that helps.
