Controlling lighting ratio • When the master flash unit is set at TTL auto or non-TTL auto flash mode, you can vary the light output amount of the master flash unit by changing lens aperture (and aperture value set on the master flash unit). • To vary the light output amount of the slave flash unit when it is set at non-TTL auto flash mode, change the aperture value set on the slave flash unit. Set one-step smaller value to reduce amount of light output to 1/2; set one-step larger value to double the amount of light output. • When the flash unit is set at manual flash mode, vary light output amount as desired. (Manual light output adjsutment is possible with the SB-26, SB-25 and SB-24.) For 1:1 lighting ratio For your convenience, the following shows how to set and locate the master and slave flash units for 1:1 lighting ratio. With a slave flash unit set at non-TTL auto flash mode: For 1:1 lighting ratio, read the aperture value on the master flash unit (same as the aperture set on the lens), set it on the slave flash unit's LCD panel then locate the slave flash unit within the flash shooting distance range indicated on the LCD panel. With a slave flash unit set at manual flash mode: Set any light output amount on the slave flash unit. For 1:1 lighting ratio, read the aperture value on the master flash unit (same as the aperture set on the lens), set it on the slave flash unit's LCD panel then locate the slave flash unit at the flash shooting distance indicated on the LCD panel. 130 Test firing Test firing is recommended. Making sure the Wireless Slave Flash selector of the slave flash unit set at "D" or"S", press the open-flash button on the master flash unit for test firing. If the slave flash unit does not fire, adjust the direction of the slave unit's Wireless Slave Flash sensor. Or use a reflector so that the slave unit's Wireless Slave Flash sensor catches the light from the master unit. Bracketing your exposure If possible, take additional shots with different lighting ratios and or flash units' locations. Chapter 4 Multiple Flash Photography Multiple Flash Photography Using Cords Depending on which terminals are used to connect flash units, TTL multiple flash photography or manual multiple flash photography will be performed. In TTL multiple flash photography, the camera controls flash exposure of all flash units connected (pages 134 to 135); in manual multiple flash photography, each flash unit is set to manual flash mode.
