Automatic High Speed Flash Sync Without Losing Power!

Studio flash used to be difficult. Even with a fully automatic DSLR, once you plugged in a studio flash unit you were on your own. Profoto changed all that with its B1 flash unit and remote control units which allow Canon and Nikon users to shoot both wirelessly and fully automatically.

The only thing missing was HSS - High Speed Sync - which allows you to shoot at shutter speeds faster than the sync speed (usually 1/250 second or slower). Being able to sync your flash at, say, 1/1000 second is a great help, especially if you are trying to capture the action. It could also be helpful for shooting outdoors with studio flash as a fill in, giving you a wider range of shutter speeds and apertures to work with.

So, if you need HSS, you went back to the on-camera flash units, but even then this wasn't completely satisfactory because to access the HSS settings, you lost quite a bit of power.

Well, now you can have your cake and eat it too. Profoto has added a new HSS feature to its B1 Off-Camera studio flash units. The B1 is about ten times as powerful as the average speedlight and fast enough (recharging) to keep up with most camera's continuous frame rate.

With the new HSS upgrade installed, you switch to HSS Mode with a simple button-press. You will then be able to shoot at shutter speeds as fast as 1/8000 of a second. Even better, you don't lose lots of power!

Now you can shoot with a large aperture in bright conditions to get a shallow depth-of-field and get that perfect deep blue sky. Or capture super crisp action in mixed light conditions without getting motion blur from ambient light.

Profoto HSS works with for both Canon and Nikon and has been tested for all common camera models. If you already have a B1, the Profoto HSS feature is available through a firmware upgrade. Go to and download it for free.
