All] Using multiple slave Speedlites as one flash unit
Convenient when you need a large flash
output. All the slave units will fire at the
same output and be controlled to obtain
a standard exposure.
No matter which firing group (A, B, or C)
the slave units belong to, they will all fire
as one group.
