Basic Operations
“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
i
(Red-eye reduction auto flash) in Picture mode or
j
(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)
