TO CREATE NATURAL-LOOKING STREAM OF UGHT-REAR-CURTAIN SYNC
Normally in flash synchronization, the Speedlight fires at the beginning of the exposure. When the shutter speed is low, the result is an unnatural light pattern.
When Rear-Curtain Sync is set, the Speedlight fires at the end of the exposure, turning available light into a stream of light that follows the flash-illuminated moving subject.
Since Rear-Curtain Sync is especially effective at a slow shutter speed, Slow Sync is automatically set at the same time that Rear-Curtain Sync is set in the Auto-Multi Program or Aperture- Priority Auto exposure mode. However, to set a desired shutter speed, set the N90 to Shutter-Priority Auto or Manual exposure mode.
•When the SB-25 or SB-24 is used, note that the Rear-Curtain Sync setting on the camera body is ignored. So you have to set the speed light unit itself for Rear-Curtain Sync.
•Rear-Curtain Sync cannot be set with Vari-Program
| • Rear-Curtain Sync cannot be set if Red -Eye Reduction (p. | Rear-Curtain Sync with low shutter speed |
| 144) has been set. |
