High speed sync is basically triggering your flashes at more than the FP (focal plane) sync limit. The usual FP sync limit like my Nikon is at 1/250 shutter speed. One of the benefits of engaging high speed sync is one can achieve shallow DOF (depth of field) especially on an outdoor environment. Photo taken during the Leysamfoto Creative Portraits workshop, this one was done outdoor at 1/1000 shutter speed with 2 SB-800 flashes with shoot-through umbrellas mounted. The shot was triggered by Pocketwizard Flex which is capable of remote high speed sync.
Did I have a blast during the workshop? You bet, most likely I was in high speed sync LOL!
