red eye reduction
Camera demon-pupil prevention
Red eye reduction is a camera feature that minimizes the red glow that appears in subjects' pupils when flash photography is used in dim light.
The red comes from light reflecting off blood vessels in the retina.
Red eye reduction typically fires a series of pre-flashes or shines a light before the main exposure, causing pupils to constrict: Make sure red eye reduction is turned on before taking the group photo.
