Wireless Multiple Flash-unit Photography
As a basic guide, the effective distance between the master and
remote flash units is up to approximately 10 m (32 ft) in the
forward-facing position, and approximately 7 m (22 ft) at both sides.
These ranges vary slightly depending on ambient light.
There is no limit to the number of remote flash units that can be
used together. However, when using many remote flash units, light
may be unintentionally picked up by the light sensor of the master
flash unit and interfere with correct functioning. Therefore, the
number of remote flash units used for wireless multiple flash-unit
photography should be limited to around 3 for 1 group.
Place all remote flash units in the same group close together and
facing the same direction.
