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 amazing picture can be ruined by this. Technically, this is called red-eye & is caused when the pupil of your subject's eye is wide open & 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.
Plenty of picture editing programs include a red-eye correction filter, but this may not permit your photograph subject to appear "normal. These filters also do not work on the green effect produced in a pet's eyes. Picture stores sell pens that are used to clear up red-eye, but again they are not always natural-looking & do not work on the green. The best thing is to prevent the demon-eye effect from the beginning.
It is rare to discover 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 & 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 & reduce the chances of this undesirable disease. Between bouncing the flash & using your digital camera's red-eye reduction feature, your tiny angel, whether human or animal, will have eyes that don't glow.
