Was going through my blogroll (on the right of my blog if yer reading this on FB) and came across a video done by noted National Geographic photographer Joe McNally. He is into high speed synch for capturing movement and posted a video of a shoot in the desert with a couple of dancers. Check out his lighting rig with the bank of flash heads on a mast held by an assistant. First seen at :48sec. The final image was 1/8000th of a second. :)
If you are on FB, you won't see the video so check it out on my blog.
