Using the red-eye reduction lamp before taking a flash picture can
reduce red eye.

On/Off], then press <0>. Select
[On], then press <0>.

3 Using Red-eye Reduction
For close subjects, the subject should be at least 1 meter/3.3 feet away
when using flash.
Detach the lens hood and keep at least 1 meter/3.3 feet away from the subject.
If the lens has a hood attached or you are too close to the subject, the
bottom of the picture might look dark due to the obstructed flash. If you
use a telephoto lens or a fast lens and the built-in flash is still partially
obstructed, use an EX-series Speedlite (sold separately).
The red-eye reduction feature is most effective when the subject looks at the red-
eye reduction lamp, when the room is well lit, or when you go closer to the subject.
When you press the shutter button halfway, the
display on the viewfinder bottom will gradually turn
off. For best results, take the picture after this display
turns off.
The effectiveness of red-eye reduction varies depending on the subject.
