Wireless flash control range
Position the wireless flash units with their remote sensors facing the camera. The following
illustration shows the approximate ranges at which the flash units can be positioned. The
actual control range varies with local conditions.
•
We recommend using a single group of up to
three remote flash units.
• Remote flash units cannot be used for second
curtain slow synchronization exposures longer
than 4 seconds.
•
If the subject is too close to the camera,
the control flashes emitted by the camera
flash may affect exposure (this effect can be
reduced by reducing the output of the camera
flash by, for example, using a diffuser).
