Rear-curtain flash sync

Cameras in Groups I through III featuring a rear-curtain flash sync mode

(F5, F100, F90X/N90s, F90-Series/N90, F80-Series/N80-Series, F70-Series/N70, F65-Series/N65-Series, F-601/N6006 and Pronea 600i/6i cameras only)

In normal flash synchronization, the SB-28 fires at the beginning of the exposure just after the front shutter curtain opens. When shooting fast- moving subjects at slower shutter speeds, this usually results in unnatural-looking pictures where the subject frozen by the flash appears behind or within the blurred movement.

In rear-curtain flash sync, the flash fires at the end of the exposure, just before the rear curtain closes, creating a picture in which the frozen subject is in front of the blurred action.

•Because the SB-28 does not have its own rear-curtain control, only those cameras with a rear-curtain flash sync mode can perform this function by setting it on the camera.

•No rear-curtain flash sync indicator appears on the SB-28’s LCD panel even when this mode is set on the camera.

•In multiple flash setups, the main flash unit can be set to either front-curtain or rear- curtain flash sync. The secondary units, however, cannot be set to rear-curtain flash sync.
