Flash modes and functions
*1 Auto Aperture flash is automatically set. When the SB-900 cannot receive lens
information such as focal length and aperture, the flash mode automatically switches
to Non-TTL auto flash.
*2 If another photographer uses the same type of wireless remote flash setup close by,
your remote flash units may accidentally fire in sync with that photographer’s master
flash unit. To avoid this, use a different channel number.
In this mode, set the following items on either the master flash unit or the remote
flash units.
