High Speed Synchronize ( HSS )
Flashgun supports shutter speed limitation on X-Sync (maximum speed synchronize
to flash) on SLR / DSLR /Mirrorless Cameras in general. If it does not support
HSS function of the camera, the shutter operation movement will block the flashgun.
As the result, higher shutter speed will block the normal flashgun with a black color
which looks like there is no flash add-on to the image(missing fire). HSS allows flashgun
works under high speed shutter (max 1/8000s).
Air 10s (Canon ) HSS On & Off switch
Method A
Hold button for 2 seconds to turn on or off.
Method B
1. Insert Air 10s to Canon camera shoe.
2. Switch on both Air 10s and Camera, go to Menu setting in the camera:
External Flash setting > select HSS mode in the sync setting
Exposure setting under HSS mode
The flash emitting operation in HSS mode is different from the normal flash mode.
With the HSS function, users can get a faster shutter speed which will result in
a lower guide number. This is equivalent to a lower flash output. The flash of HSS
cannot be measured by an external light meter. When HSS is on,
the exposure compensation setting of TTL mode offers the same -2EV to +2EV of
basic mode. Using the power control of "M" Manual mode under HSS,
the Air 10s offers 1/32 to 1/1 power range only. If power is set from 1/256 to 1/64+0.3EV,
"M" manual power setting will automatically change to 1/32 in HSS mode.
