A method of reducing or eliminating red-eye from flash photographs by using a short burst of light, or pre-flash, to momentarily “stop-down” the pupils of the subject’s eyes prior to the actual flash exposure. Some cameras have a built-in pre-flash that fires several times to coax the pupils into contracting, before making the final flash and image capture. Red-eye can also be eliminated electronically after the fact in many photo-editing programs. Many digital cameras contain software applications that electronically eliminate red-eye in-camera, as well.
