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 <S>, 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.
• When the red-eye reduction lamp lights up, the
shutter will not release for about one second. This
is to increase the effectiveness of the red-eye
reduction function. If you want to shoot right away,
turn the red-eye reduction function off with the
KS> flash mode button.
