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 of the camera, 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.
For details on setting the HSS features, see “Custom setting” (page 74).
Flash Sync Speed
Flash photography is generally associated with a maximum shutter speed referred to as the flash sync speed. This restriction does not apply to cameras designed for high-speed sync (HSS) photography, since they allow flash photography at the maximum shutter speed of the camera.
