Optical Transmission Wireless Flash Shooting - Canon Speedlite 430EXIII-RT Instruction Manual

: Optical Transmission Wireless Flash Shooting

Using a Canon device with an optical transmission wireless master
function and 430EX III-RT/430EX III set as a slave unit makes it easy to
shoot with wireless multiple flash lighting in the same way as normal E-
TTL II/E-TTL autoflash shooting.
The system is designed so that the settings of the master unit are set
automatically on the 430EX III-RT/430EX III (slave) that is wirelessly
controlled. Therefore, you do not need to operate the slave unit during
shooting (except when set as the individual slave, p.78).
For details on how to perform optical transmission wireless flash
shooting, refer to the instruction manual of the device equipped with the
master function.
