Using the Built-in Flash

104

When flash is used in a low-light environment, the subject’s eyes may 
look red in the image. “Red eye” happens when the light from the flash 
reflects off the retina of the eyes. The camera’s red-eye reduction 
feature turns on the red-eye reduction lamp to shine a gentle light into 
the subject’s eyes to narrow the pupil diameter or iris. A smaller pupil 
reduces the chances of red eye from occurring. Red-eye reduction can 
be set in any shooting mode except <3> <5> <7>.

 

Turn the <5> dial to select [z Red-
eye On/Off], then press <0>.

 

Turn the <5> dial to select [On], 
then press <0>.

 

When you exit the menu, <L> will 
be displayed on the LCD panel.

reduction lamp

On indicator

 

When you press the shutter button down 
halfway, the red-eye reduction lamp 
indicator appears in the viewfinder.

 

Red-eye reduction will not be effective unless the 
subject looks at the red-eye reduction lamp. 
Tell the subject to look at the lamp.

 

To increase the effectiveness of red-eye reduction, 
press the shutter button down completely after the 
red-eye reduction lamp (which lights for approximately 
1.5 seconds) indicator goes off.

 

You can shoot anytime by pressing the shutter button down completely, 
even while the red-eye reduction lamp is still on.

 

The effectiveness of red-eye reduction varies from subject to subject.

 

Red-eye reduction is more effective in brighter rooms or when the 
camera is closer to the subject.
