When you use flash in low-light conditions, it can reflect off your subject's pupils and make their eyes look red in the recorded image. This effect is called "red-eye," and is caused by the light of the flash reflecting off the retina of the eye. The Red-eye reduction function uses the camera's red-eye reduction lamp, which gently shines into the subject's eyes to constrict the pupils and thereby reduces the likelihood that red-eye will occur. You can use red-eye reduction in any picture-taking mode except <> and <> modes.

From the menu, select [Red-eye on/off]. Press the <MENU> button. Turn the <> dial to select [Red-eye on/off], then press the <SET> button. Set the Red-eye reduction function. Turn the <> dial to select [On], then press the <SET> button. The red-eye reduction function is turned On, and the display returns to the Menu. Press the <MENU> button to clear the screen and exit the menu.

• When you press the shutter button down halfway, the redeye reduction lamp indicator appears in the viewfinder.
• Red-eye reduction is effective only when the subject is looking at the red-eye reduction lamp. Be sure to tell your subjects to look at the lamp.
• To increase the effectiveness of red-eye reduction, press the shutter button down fully after the red-eye reduction lamp (which lights for approximately 1.5 seconds) indicator goes off.
• You can take a picture anytime by pressing the shutter button down fully, even if the red-eye reduction lamp is on.
• Red-eye reduction also operates when you use an EOS dedicated Speedlite.
• The effectiveness of red-eye reduction varies from subject to subject.
• Red-eye reduction is more effective in bright interior locations, with the camera closer to the subject.
