Why do eyes turn red during photographs?

Question

Please don't insult me with answers like "the flash." Why does the flash give you red eye? Please include links. Thanks!

Answer 1

ok lets not say the flash lets say " the pumpkin"


your eyes arent turned red,

its because people want small cameras, so the designers make them small - the problem is the pumpkin is to close to the lens and the blood in the back of the eyes is reflected straight back to the lens

people who know photography use off camera pumpkin or the pumpkin on a pumpkin bracket

no links - just look at any small camera and note how close the lens and pumpkin are to each other -

LOL, Antoni has it.

I always try to give value-added, so here's an explanation of some ways to avoid red-eye.

1. Don't use the pop-up built in flash on the camera. A hotshoe flash is better, but still can cause red-eye if used directly.
2. Use the swivel head if your flash has one, and bounce light off the wall or a ceiling.
3. Use a bracket to get the flash further from the lens if you can't bounce.
4. Get the flash off the camera entirely! Check out strobist.blogspot.com for more details.

Answer 4

Unfortunately, though there are hundreds of theories surrounding what causes red eye, none of them have been 100% proven. Some have been about 95% accurate but that's all the further. Try not to use an on camera flash. If possible, use an external flash mounted above the hotshoe of the digital camera. This will keep the flash from entering directly into the retina of the eye and bouncing back at you. Animals eyes are very sensitive to light (which is why they glow so easily at night) and will reflect the slightest hint of light.

Answer 5

Reflection in the retina when the flash is too close to the lens. If you are dealing with a point and shoot, turn on as many lights in the room to reduce the pupil ( I wouldn't give you a dime for that "red eye reduction" feature) or photograph the person with the camera slightly above them and tilted down.

Answer 7

The Flash Will Reflect From Your Eye Which Will Change The Color.

Answer 8

It's the light being reflected back at the camera from the retina of te eye, it can be reduced/eliminated by having an offset flash (not having the flash and the lens close together.

Answer 9

The the flash of light causes the iris to open wider than usual, allowing the light to reflect from the inside back of the eyeball. This usually happens when looking almost directly into the flash.

Answer 10

The red is actually a reflection off your pupil (eye lens). The angle that the flash strikes the shape of your pupil can cause red-eye if the light reflects back at exactly the right angle..

To prevent red eye, you want the flash located as far away from the lens of the camera as possible so as to increase the angle the light hits and thus Decrease the angle reflected back to the camera lens...

Answer 11

The light reflecting off the retina. Here's a link on how to get rid of it either by changing the way the picture is taken or afterwards using computer software.
