Wireless Slave Flash Photography When used as a slave flash unit, the SB-26 will fire when its Wireless Slave Flash sensor catches light from the master flash unit. For Wireless Slave Flash photography, the SB-26's Wireless Slave Flash selector provides two positions-"D" ("delay" mode) and "S" ("simultaneous" mode). In "delay" mode, the SB-26 used as a slave flash unit will fire a moment after the master flash unit fires, without affecting the master flash unit's flash exposure control. In "simultaneous" mode, the SB-26 as a slave unit will fire at the same time as the main flash unit fires. When perfoming Wireless Slave Flash to eliminate harsh shadows in TTLauto or non-TTL auto flash mode, the master flash unit's flash exposure control may be affected by the light from the slave flash unit, resulting in underexposed subject. (See photos at right.) When the Wireless Slave Flash selector set at "D" or "S", U appears in the LCD panel. For Speedlights without Wireless Slave Flash function Use the TTL multiple flash terminal or sync/multiple flash terminal on the SB-26 (used as a slave flash unit) to connect a Speedlight without Wireless Slave Flash function via a sync cord SC-18/SC-19 or SC-11/SC-15. The connected Speedlight(s) will fire at the same time the SB-26 (slave flash unit) fires. 128 SB-26 S D OFF SB-26 S D OFF Chapter 4 Multiple Flash Photography Settings on flash units and camera • Set the SB-26's wiresless slave flash selector to "D" or "S". If two or more SB-26 units are used-one as a master unit, the other as slave unit(s) or all as slave units-set the Wireless Slave Flash selector on all units to the same setting. With the Wireless Slave Flash selector set at "OFF", the SB-26 as a slave flash unit does not fire when the Wireless Slave Flash sensor catches the light. • Set the flash mode selector of the master flash unit to TTL auto, non-TTL auto or manual, as you like. Do not set FP High-Speed sync when the SB-26 or SB-25 is used as a master flash unit. • Set the flash mode selector of SB-26 used as a slave flash unit to non-TTL auto or manual. TTL auto flash is not suitable. • Set the camera's exposure mode to Aperture-Priority Auto or Manual exposure mode and set the desired aperture on the lens. • Locate the master flash unit within the flash shooting distance range (for TTL auto or non-TTL auto flash mode) or at the flash shooting distance (for manual flash mode). If camera/Speedlight combination does not offer automatic aperture adjust ment on the Speedlight, you must first set the aperture value (same as set on the lens) on the Speedlight. • For "delay mode", set the camera's shutter speed onestep slower than the camera's synchronization speed. (When using the F5, F90X/N90s, F70-Series/N70 or F4Series camera and the SB-26 as a master flash unit, this is not necessary because the shutter speed is automatically switched.) • When using the F5, F90-Series/N90 or F70-Series/N70 cameras, note the following: with the SB-26 as a master flash unit set at TTL auto flash mode, Monitor Preflashes will be automatically cancelled when the multiple flash selector set at "D" or "S". With the SB-25 as a master flash unit set at TTL auto flash mode, avoid Monitor Preflashes by upward tilting or rotating the flash head. If you should not do so, Monitor Preflashes will cause the slave flash unit to fire before shutter release. • With the Wireless Slave Flash selector set at "D" or "S", the STBY position does not automatically turn off the SB-26. • For rear-curtain sync, set the Wireless Slave Flash selector on master and slave flash units to "S". • In "delay" mode, rear-curtain sync is not recommended. • Make sure that the slave flash unit is disconnected from camera body or connected camera power is off. 129
