Auto Aperture Mode - Vello FWIRC-N User Manual

AUTO APERTURE MODE

In Auto Aperture (AA) mode, your
flash's built-in sensor will automatically
set the appropriate flash power output
level by measuring the reflected
light from the environment. This
is different from i-TTL, which uses
your camera's exposure sensor.
AA mode and EV are set
independently for each group.
