REAR-CURTAIN SYNC FLASH-For Natural Light Flows

When used with the F4 or F-801/N8008, the S8-24 lets you synchronize the flash to the instant before the rear (second) curtain begins to close.

Set the S8-24'sflash sync mode selector to "REAR." This turns available light into a stream of light that follows the flash-illumi- nated moving subject.

Rear-curtain sync flash photography is most effective with slower shutter speeds. Although the slowest possible shutter speed for front-curtain sync flash photography in TTL mode (with camera at PO, P, PH or A) is only 1/60 second, with rear- curtain sync flash photography, depending on the background, you can slow the shutter down to 30 seconds.

eln shutter-priority auto or manual exposure mode, be sure to select an appropriate shutter speed. In programmed auto or aperture-priority auto exposure mode, confirm shutter speed is not too slow. Otherwise, it could affect image sharpness. To prevent camera shake, use a tripod.

e Rear-curtain sync flash is available when flash mode selector is set to TTL, A or M.
