Nikon SB-24 NON-TTL Auto f!1, S8-24 offers two types of flash synchronization, Rear

NON-TTL AUTO f!1

In this mode, light is read through the light sensor on the front of the S8-24, instead of being measured through the lens. Exposure control requires that you manually adjust the lens aperture. For non-TTL auto flash mode, see pages 66 to 68.

MANUALli!il

Lets you select flash power from full power of 1/16 power and set aperture according to flash-to-subject distance. Indicated on the LCD panel.

For manual flash , see pages 70 to 76.

REPEATING FLASH lillI

This mode lets you flash a subject two or more times consecutively in the same frame. It enables you to select the number of flashes, flash speed (Hz) and power-either 1/8 or

1/16.

For detailed instructions on repeating flash, see pages 77 to 80.

FLASH SYNC MODE SEl.!ECTOR-

The S8-24 offers two types of flash synchronization, REAR and

NORMAL.

NORMAL synchronization, the way virtually all other systems operate, fires the flash at the beginning of the exposure. REAR synchronization, available with the Nikon F4 or F-8011N8008, fires the flash at the end of the exposure.

For short exposure (speeds up to 1/250 second) you can barely tell the difference between the two methods. For longer expo- sures, however, when subject movement during the exposure becomes evident, you can clearly see the difference.

Rear synchronization tends to give a more natural effect, making the blur of subject movement appear to emanate from the back for a more comfortable visual effect.

For details, see page 48.
