Test Flash and Modeling Flash with a Slave Unit

In radio transmission wireless shooting, you can fire the test flash and 
modeling flash (p.36) from a 430EX III-RT set as a slave unit.

Select <N> or <M>.

 

Press <8> of the slave unit.

 

Turn <9> to select <N> or 
<M>, then press <8>.

A flash signal is sent from the slave unit 
to the master unit, and a wireless system 
test flash or modeling flash is fired.

 

While the flash mode can be set to </> auto external flash metering 
when 430EX III-RT is set as a master unit, this function is effective when 
using a slave unit that supports </> (example: 600EX-RT).

 

430EX III-RT does not support </>. As a result, when the flash 
mode of the master unit is set to </>, 430EX III-RT units set as the 
slaves do not fire. When using 430EX III-RT as a slave and setting the 
flash mode with the master, do not set the flash mode to </>.

 

When 430EX III-RT is set as the master unit and the flash mode of firing 
group “A” is set to </>, master flash firing is not performed even if 
430EX III-RT is set to “Master flash firing: ON” (p.53).

 

When the flash mode is set to <a> or </>, exposure is 
controlled as a single group to obtain the standard exposure for the main 
subject. If you shoot with multiple firing groups pointing toward the main 
subject, overexposure may result.

 

For </>, refer to the instruction manual of a Speedlite compatible 
with auto external flash metering.

 

When you do not want a certain group to fire, select <E> when 
setting the flash mode in step 3.

 

The order of firing among firing groups does not need to be consecutive; 
for example, A, C, E can be set.

 

You can set the flash output or flash exposure compensation amount by 
simply pressing <8>, selecting the firing group using the <S> cross 
keys, and turning <9> (P.Fn-08/p.88).
