Luminar AI - How To Fix Red Eye

Red Eye Removal Red eye occurs in flash photography. It is caused by the flash occurring too fast for the pupil to react and close. The bright light from the flash then reflects off the back of the eyeball.

The Red Eye Removal slider automatically detects this phenomenon in your images and can remove the red glow, and replace it with black. Moving the slider to the right increases the intensity of the effect, so you basically just go ahead and move the slider until the offending red eyes have been completely eliminated.
