Today, we release Profoto HSS – our new solution for the B1 Off-Camera Flash that has all of the benefits and none of the limitations. We figured you guys will have a lot of questions. Don’t worry, you will find the most common questions in the FAQ below.
In addition, there will be a bunch of more specific questions in the comment section. For your information, this page will continuously be updated. So if you have a question that isn’t answered here, leave a comment or tweet us, and we’ll insert it into the FAQ as soon as we can.
1) What is HSS?
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. With HSS, you can shoot at shutter speeds up to 1/8000.
2) What is HSS used for?
Having super short flash duration allows you to shoot with a large aperture in bright conditions to get a shallow depth without burned out skies. You can also capture super crisp action in mixed light conditions without getting motion blur from ambient light.
3) How is Profoto HSS different?
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. Add to that the fact that the B1 itself is about 10 times as powerful as your average speedlight and fast enough to keep up with your camera. In short, it is fast, powerful and consistent, allowing you to do things that were not possible before.
4) What products do I need to use Profoto HSS?
You need a Profoto B1 Off-Camera Flash and either an Air Remote TTL-C (for Canon) or an Air Remote TTL-N (for Nikon). Also, you need a Canon or a Nikon camera, of course.
