How Does Red Eye Reduction Work?
Reduce Red Eye By Changing the Light Have you noticed that when you take pictures of people who aren’t looking at the camera, they never have “horror movie eyes” with red pupils? That’s because of the angle of the light from the flash. Red eye in photos happens when light reflects off the blood vessels in the eye. When your subject doesn’t look directly at the camera, you reduce red eye. When you open the curtains and use natural light, instead of the flash, or take pictures outdoors, in natural light, no red eye. It also helps when you walk in for a close up, rather than zoom in. Zooming in brings the lens closer to the eye. Reduce Red Eye with a Camera Feature There are digital cameras equipped with a red eye reduction feature. They actually flash low level light at the subject before the picture is ever taken. This constricts the pupils in the eye, and then when the picture is taken the real flash doesn’t light up the blood vessels in the pupil. Camera stores also sell special pens
