Up until now, HSS solutions have been either consistent but lacking in speed and power, or fast and powerful but inconsistent. Today, we release Profoto HSS – a new solution that has all of the benefits and none of the limitations.
High-Speed Sync (HSS) is the technical term for syncing flash with shutter speeds shorter than the so-called x-sync, typically 1/250 of a second. It is a useful tool for controlling ambient light and for freezing action. But there used to be limitations.
Current solutions for speedlights give you a fairly even exposure. But it does so at the expense of speed and power. Previous solutions for larger flashes were faster and more powerful. But the exposure could differ as much as 2 f-stops in a single shot.
Profoto’s new solution for the B1 Off-Camera Flash has all of the benefits and none of the limitations. The B1 itself is about ten times as powerful as the average speedlight and fast enough to keep up with your camera. With the new Profoto HSS upgrade installed, you switch to HSS Mode with a simple button-press. You will then be able to shoot at shutter as fast as 1/8000 of a second.
But it does not stop there. Profoto HSS is a unique, patent-pending technology, providing an extremely fast series of flash pulses. What this means in practice is that you get an extremely consistent exposure with no measurable variation over the image.
