[About the red-eye phenomenon]
Taking pictures using the flash may cause the subject's eyes to
appear red in the resulting picture. This phenomenon occurs when
the light from the flash is reflected in the subject's eyes. It can be
reduced by illuminating the area around the subject or moving closer
to the subject and zooming out to a wider angle. Setting the flash
mode to c (Auto + Red-eye) or d (Flash On + Red-eye) is also an
effective way of reducing red eyes.
