ADVANCED FEATURES

High-Speed Sync Mode

You can use shutter speeds that are
faster than your camera's maximum
flash sync speed with the FreeWave IR
Commander by activating high-speed
sync (HSS). HSS lets you use shutter
speeds as fast as 1/8000 second. This
is helpful when shooting with large
apertures in brightly lit environments
or when freezing motion.

In HSS mode, the FreeWave
IR Commander will wirelessly
transmit the information from
your camera to your flash.
You can enable HSS either by pressing
the FN button on the Commander
or your camera's flash menu
screen. When HSS is enabled, the
FP icon [ ] will appear in the top
right corner of the Commander's LCD.
