Red Eye Reduction
The flash strobes two or more times before shooting to reduce the red-eye phenomenon when
using the flash.
1 MENU t
(Red Eye Reduction)
t desired mode
• [Red Eye Reduction] cannot be selected during Movie Mode or Smile Shutter.
• To avoid blurring of images, hold the camera firmly until the shutter is released. It usually takes a second
after you press the shutter button. Be also sure not to allow the subject to move during this period.
• Red Eye Reduction may not produce the desired effects. It depends on individual differences and
conditions, such as distance to the subject, or if the subject looked away from the pre-strobe.
• If you do not use the Face Detection function, Red Eye Reduction does not work, even when you select
[Auto].
(Auto)
When the Face Detection function is activated, the flash strobes
automatically to reduce the red-eye phenomenon.
(On)
The flash always strobes to reduce the red-eye phenomenon.
(Off)

What causes the red-eye phenomenon?
Pupils become dilated in dark environments. Flash light is reflected off the blood vessels at
the back of the eye (retina), causing the “red-eye” phenomenon.
Other ways to reduce red-eye
• Select
(High Sensitivity) mode in Scene Selection. (The flash is set to [Flash Off] automatically.)
• When the eyes of the subject turn out red, correct the image with [Retouch]
t [Red Eye
Correction] on the viewing menu or with the supplied software “PMB”.
