Using red-eye reduction flash
“Red-eye” is the phenomenon where eyes look reddish in
photographs taken in dark environments with a flash. This is caused
by the reflection of the electronic flash in the retina of the eye.
Red-eye occurs because pupils are dilated in dark environments.
This phenomenon cannot be averted but the following measures can
be used to combat it.
Brighten the surroundings when shooting.
Set to wide angle and move closer to the subject if a zoom lens
is in use.
Use a flash that supports red-eye reduction.
Position the flash as far away from the camera as possible when
using an external flash.
The red-eye reduction function on this camera reduces red-eye by
discharging the flash twice. With the red-eye reduction function, the
pre-flash is discharged just before the shutter is released. This
reduces pupil dilation. The main flash is then discharged while the
pupils are smaller, reducing the red-eye effect.
To use the red-eye reduction function in Picture mode or H (Scene)
mode, select D or F. Set to F or H in other modes.
