The Modeling Light; Autofocus Assist - Vello FWIRC-N User Manual

The Modeling Light

The modeling light gives the appearance
of a continuous light so you can
approximate how the flash will illuminate
your subject, and is available on cameras
that have a Depth of Field Preview
button. To activate the modeling light
feature, press your camera's Depth of
Field Preview button. The flash will pulse
rapidly to simulate the direction of light.
Note: Using the modeling light will greatly
decrease your batteries' output.
