What is High-Speed Sync?

HSS or High-Speed Sync, enables you to use flash at any shutter speed up to 1/8,000 of a second. That means you are in full control of the ambient light, which is useful when shooting outdoors in sunlight. With HSS you can shape light even with large apertures and at fast shutter speeds. HSS is great for outdoor portraits with shallow depth of field or freezing fast action in broad daylight. Profoto HSS is faster, more powerful and more consistent than any other HSS solution on the market.
