Red-eye removal is the correction of red-looking pupils in a flash photograph. The red effect comes from flash reflecting from the retina, often in low light; removal tools detect or let you select the reflection and darken it. You can correct an existing image in an editing app or a camera’s retouch menu, and reduce the chance of it happening in future shots.
What red-eye removal means
Nikon defines red-eye as red spots in the center portions of a subject’s eyes in flash pictures. “Red-eye removal” refers to correcting those spots in an image. Adobe explains that the effect is caused by flash reflections from the retina and is common in low-light settings. Adobe’s Photoshop help and Nikon’s photography glossary describe the effect.
How to remove red eye from an existing photo
The steps depend on the app or camera. Some tools find the reflection automatically; others ask you to mark the pupil. Check the result afterward, since automatic correction can miss red eye or alter an unaffected area.

On a Nikon camera
Nikon’s D780 manual describes a Red-Eye Correction option in the camera’s retouch menu. It applies only to photographs taken using flash. The camera may not detect every instance, and its correction can be imperfect, so check the preview before accepting the result. See Nikon’s D780 Red-Eye Correction instructions.

How to reduce red eye in future photos
Adobe recommends using your camera’s red-eye reduction feature or using a flash away from the lens. These approaches help prevent the effect during photography; they do not remove red eye from a photo that has already been taken. See Adobe’s Photoshop help.
