Su-4 Type Wireless Multiple Flash Shooting - Nikon SB-800 Instruction Manual

SU-4 type wireless multiple flash shooting

SU-4 type wireless multiple flash can be performed in two ways: (1) In the A
(auto) mode, in which the wireless remote flash units start and stop firing in
sync with the master Speedlight, and (2) in the M (manual) mode, in which the
wireless remote flash units only start firing in sync with the master Speedlight.
• Speedlights featuring wireless multiple flash capability can be used either as the master
or remote flash unit.
• Speedlights compatible with TTL auto flash can be used as the master flash unit. The
optional Wireless Slave Flash Controller SU-4 is necessary when you want to use these
Speedlights as remote flash units. The one exception is the SB-23.
• The camera's built-in Speedlight can also be used as a master flash unit.
• There is no limitation in usable cameras.

Setting the SB-800 to SU-4 type wireless multiple flash
To perform SU-4 type wireless multiple flash, set the wireless flash mode to
"SU-4" using Custom settings (p. 67).
Master flash and remote flash units
• First, set the SB-800's wireless multiple flash mode to "SU-4" using the Custom settings,
then attach the SB-800 to the camera. The indicator O appears on the LCD panel
telling you that the SB-800 is set as a master flash unit. If you detach the SB-800 from
the camera, the indicator automatically changes to P signifying that the SB-800 is set
as a remote flash unit.
Notes on the master flash unit
• When the SB-800 is set as the master flash unit, Monitor Preflashes are canceled. For
other Speedlights, be sure to cancel the master flash unit's Monitor Preflashes.
• The following flash modes are recommended for the master flash unit.
