From the Profoto YouTube archives:
"What's the Difference?" is a series of video lighting tutorials. Each episode responds to a single question. In this episode, Jared Platt tries freezing motion with the High-Speed Sync.
Jared Platt does an outstanding job in every video, but I especially loved the way he takes you through high speed sync in this one, along with his explanation of high speed sync in a previous video I shared. Like the previous video on high-speed sync, Jared and Profoto demonstrate each exposure along the way, from ambient and blurred movement to completely freezing the key elements in the image.
