41 Taking Pictures and Recording Video Clips
If the flash setting is anything other than the default Auto
Flash setting, the icon for the setting will appear in the Live
View screen. The new setting remains in effect until it is
changed again or until the camera is turned off. The flash
setting resets to the default Auto Flash setting when you turn
the camera off.
NOTE: To restore the flash setting to what it was when you
last turned the camera off, hold down the button as
you turn the camera back on.
Red Eye
The red-eye phenomenon is caused by light from the flash
reflecting off the subjects’ eyes, which sometimes makes a
human’s eyes appear red or an animal’s eyes appear green
or white in the captured image. When you use a flash setting
with red-eye reduction, the camera flashes quickly up to three
times to minimize the subject’s pupils, thus reducing the effect
of the red-eye phenomenon, before the camera uses the main
flash. It will take longer to take a picture using red-eye
reduction, because the shutter is delayed for the additional
flashes. Therefore, make sure your subjects wait for the
additional flashes.
TIP: You can also remove red-eyes in pictures you have
already taken. See Remove Red Eyes on page 71.
