Positioning Slave Flash Units
|
39
When positioning wireless slaves to light a subject,
keep in mind the following:
• The effective communication range between master
and slave ash units is approximately 33 feet (10 m) in
the front position, and approximately 16–23 feet (5–7
m) on both sides. These ranges may vary, depending on
the ambient light.
• The ash head should not be aimed directly into the
camera lens.
• The optical sensor is located on the front of the VX-
710C. Make sure that the sensor is facing the master
ash and that there are no obstructions between the
two units.
• When photographing outdoors or in bright ambient
light, the sensors can be overwhelmed by ambient
light, which will lower their sensitivity.
