Canon EOS 20D - Manual (Page 94)

Using the Built-in Flash
94
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>.
1 Select [Red-eye On/Off].
¡ Turn the <
5> dial to select [z Red-
eye On/Off], then press <
0>.
2 Select [On].
¡ Turn the <
5> dial to select [On],
then press <
0>.
Using Red-eye Reduction
¡ When you press the shutter button down
halfway, the red-eye reduction lamp
indicator appears in the viewfinder.
¡ Red-eye reduction will not work 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 fully
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 fully, even if
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.
