Changing the Flash Mode
Red-eye Reduction Function
With flash photography in dark places, the subject's
eyes may appear red. This phenomenon is called
"red-eye" and occurs when flash illumination reflects
off the retina.
With the red-eye reduction function (® indicator),
the red-eye reduction lamp lights up to illuminate
the subject for about one second before the flash is
fired. This will minimize the chances of red-eye.
