The red-eye effect is a well-known problem in photography. It is often seen in amateur shots taken with a built-in flash, but the problem is also well known to professional photographers. This effect is caused by the reflection of the blood vessels in the retina, usually when a strong and sudden light strikes the eye. Red eye is a function of at least three things: • Ambient light level. Low level causes the subject’s pupil to open wider to admit more light, exposing the retina. © 2009 by Taylor & Francis Group, LLC

Abstract

The red-eye effect is a well-known problem in photography. It is often seen in amateur shots taken with a built-in flash, but the problem is also well known to professional photographers. This effect is caused by the reflection of the blood vessels in the retina, usually when a strong and sudden light strikes the eye. Red eye is a function of at least three things: • Ambient light level. Low level causes the subject’s pupil to open wider to admit more light, exposing the retina. © 2009 by Taylor & Francis Group, LLC
