Fixing Red Eye

You've seen it a thousand times—that “devil eye” look that spoils pictures of everyone from grandma to the new baby, puppy, or cat. Usually the eerie glow is red, but it can be green, blue, or even yellow. It's caused by light reflecting back to the camera lens from the inside of the eye, which can only happen if the pupil of the eye is open—as it would be in a dimly lit room, or outside in full shade. Red eye appears red in humans because of the network of blood vessels back there. Our four-footed friends are more likely to display green or yellow eye, although normally blue-eyed Siamese cats eyes will also glow fiery red. Figure 24.3 shows an especially awful example, with both eyes affected.
