High-Speed Sync (Hss) - Sony HVL HVL-F36AM Operating Instructions Manual

High-speed sync (HSS)

High-speed sync Normal flash
High-speed sync eliminates the restrictions of flash sync speed and enables
the flash to be used through the entire shutter speed range of the camera.
The increased selectable aperture range allows flash photography with a
wide aperture, leaving the background out of focus and accentuating the
front subject. Even when photographing at a wide f-stop in the A mode or
M mode, when the background is very bright and the shot will normally
be over-exposed, you can adjust the exposure by using the high-speed
shutter.
Press the high-speed sync button (HSS).
• The high-speed-sync lamp comes on.
