					Red Eye and Your Digital Camera
You’ve seen the dreaded demon-eye effect that occurs when the camera
flash bounces off the eye of a person or pet. An otherwise wonderful
picture can be ruined by this. Technically, this is called red-eye and
is caused when the pupil of your subject’s eye is wide open and the light
from the camera’s flash reflects off the subjects retina. In people, the
color ends up red; in pets, the color is often green.
Many photo editing programs include a red-eye correction filter, but this
may not allow your photograph subject to appear “normal. These filters
also do not work on the green effect produced in a pet’s eyes. Photo
stores sell pens that are used to clear up red-eye, but again they are
not always natural-looking and do not work on the green. The best thing
is to prevent the demon-eye effect from the start.
It is rare to find a digital camera that does not come with a red-eye
reduction feature. This feature can be turned off or on. It is best
left on in all circumstances other than direct sunlight. The red-eye
reduction feature works by flashing a short burst of light at your
subject before you snap the picture. This burst of light causes the
subject’s pupil to close and makes it less likely for the camera’s flash
to reflect off the retina. This in turn reduces the chance of red-eye.
It also helps to direct the flash of your camera so it does not directly
hit your subject’s eyes. Bouncing the flash off a nearby wall or other
object will soften its effect and reduce the chances of this unwanted
malady. Between bouncing the flash and using your digital camera’s red-
eye reduction feature, your little angel, whether human or animal, will
have eyes that don’t glow.
