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 cause the subject’s pupils to contract, 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.
