“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 shoot from closer 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, set C (Red-eye reduction auto flash) in Picture mode or D

(Red-eye reduction manual flash) in other modes for Flash mode.

In daylight conditions, the flash will eliminate shadows when a portrait
picture is taken with a person’s face cast in shadow. Use of the flash in this
way is called Daylight-Sync Shooting. Flash is discharged manually when
shooting with Daylight-Sync Shooting.

Taking pictures (Auto Picture)

1 Confirm that the flash has popped up and the flash mode is set to b

(Manual discharge). (p.51)

2 Confirm that the flash is fully charged.
