Using Red-Eye Reduction - Canon Rebel T2i EOS 550D Instruction Manual

Shooting Tips
If the subject is far away, increase the ISO speed.
By increasing the ISO speed, you can extend the flash range.
In bright light, decrease the ISO speed.
If the exposure setting in the viewfinder blinks, decrease the ISO speed.
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.
For important shots, check the image on the LCD monitor to make
sure the flash exposure looks good (not dark at the bottom).

3 Using Red-eye Reduction

Using the red-eye reduction lamp before taking a flash picture can
reduce red eye.
Red-eye reduction will work in any shooting mode except <7> <3>
<5> <k>.
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
viewfinder display on the 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.
Under the [1] tab, select [Red-eye
reduc.], then press <0>. Select
[Enable], then press <0>.
For flash photography, when you
press the shutter button halfway, the
red-eye reduction lamp will light. Then
when you press the shutter button
completely, the picture will be taken.
