Positioning Remote Flash Units
You can create a professional lighting setup by positioning remote units singly or in groups to function as main,
fill, accent, and other lights. Metering your scene with a handheld light meter and setting your light ratios to
achieve specific looks will give you a professional level of creative control.
When positioning wireless slaves to light a subject, keep in mind the following:
• The effective communication range between master and remote flash
units is approximately 33 feet (10 meters) in the front position, and
approximately 16 to 23 feet (5 to 7 meters) at both sides. These ranges
may vary, depending on the ambient light.
• The flash head should not be aimed directly into the camera lens.
• The wireless sensors are located on the front of the VS-570. Make sure
that sensor is facing the master flash and that there is no obstruction
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.
• To avoid creating interference between flash units, using more than
three in a single group is not recommended.
