Red eyes are one of the most common problems in photography. It might be wedding photography, professional headshots, corporate headshots or fashion photography. It can ruin a great photo. We’ll be explaining the reason behind the red eye and how to remove it in this article.
What causes it?
This effect occurs when a picture is taken with the camera’s flash turned on in an environment with poor lighting. It can occur in places like dark rooms, photo studios or outdoors at night. The pupils open up wide during the dark time to let in as much light as possible to make it visible for the person. When a flash is used the light enters the dilated pupils, it bounces off the back of the eye and travels back in the same direction it was sent in. If the flash is mounted close to the photography camera, then the majority of the light enters back into the lens giving a worse red-eye effect. The color red comes from the blood in the choroid, the layer which at the back of the eye. Now that sounds fascinating, but it is a photobomb for most of the people, to look like a vampire while posing for a happy shot.
