Why do your eyes sometimes turn out red in pictures?

Answer 1

If you use a flash in a dark environment, you often get a red eye effect. This is because the light of the flash is reflecting from the retina, which is covered with tiny blood vessels.

The more open the pupils are, the more red eye effect you get in your photos. Red eye is more pronounced in people with light eye color. It is also more pronounced in people with blond or light-red hair and in children.
When you take photos of animals, the red eye effect can be quite different. Animals have a reflective layer in the back of their eyes behind the retina called the tapetum. This layer enhances their night vision. The colour of the tapetum gives you blue, green, yellow, or white eye effect. With animals, the effect can have place even when the ambient light is sufficient to prevent it in humans.

Answer 2

It is an action that is caused by the flash being too close to the lens so that it does not hit the subject at an angle. You have to remember with flashes tht the angle of incidence (how the light hits the eyes in this case) is = to the angle of reflectance. So if you put your flash even as little as 8-10 inches, probably less will work also, the flash will bounce not toward the camera, but at the angle the light hits the eyes. You can also bounce your light so that the hard burst does not hit the eyes directly, but at an angle. You have to adjust for the distance. If, for instance, you are bouncing off the ceiling (and that should be white or you will get some discoloration) y ou have to calculate the distance from the flash to where it is hitting the ceiling and then calculate the distance from the spot on the ceiling to the subject. Put your flash on manual and set the distance scale to the actual distance the light is going The main problem with digitals is that many do not have a PC connector to attach an off camera flash, they have their flashes just above the lens and in shooting pictures of animals and people, you will get eye problems. Some animals have a red back of the eye, others have yellow. I have a dog who always looks like Satan himself where there is red eye. If you take a picture of an alligator, for instance, it bounces back either yellow or a yellowish orange. Explaining the anatomy of the back of the eye ball, which is where the colors come from, is of little significance, changing angles is the cure. Don't take a picture straight on the face, ask your subject to change the position of their head to the right or left.

Answer 3

It has to do with the flash from the camera making the pupils in your eyes quickly enlarge/dilate to cope with the sudden outburst of light. If the flash is off you probably won't have this problem. But since flash is often required, most photo editting softwares today have a feature that eliminates it in one click.

Answer 4

Your eyes shine because of the light.. try taking the pictures with the camera upside down.. weird, but it makes the red eye go away!

Answer 5

thats because photgraphs create an unusual phenomenon where the demon inside the person shines through their eyes and is picked up on the film, very scary!

Answer 6

The flash reflects on your subjects corneas

Answer 7

This is well known electro-magnetic process which reveals spirit possession.

Answer 8

Attempted demonic possession. You can chase them away with a fart.

Answer 9

im pretty sure its from looking at the flash

Answer 10

because light is reflected from your viens and the retinas in your eyes.
