How does red-eye reduction work in a camera to prevent the appearance of red eyes in photographs?
Red-eye reduction in a camera works by emitting a pre-flash of light before taking the actual photo. This pre-flash causes the pupils to constrict, reducing the amount of light that reaches the back of the eye and minimizing the reflection of the camera flash off the blood vessels in the retina, which is what causes the red-eye effect in photographs.
What is red eye reduction in camera and how does it work to improve the quality of photographs?
