why is it when we have a photo taken we get red eyes and dogs get green eyes ?

Answer 1

It's to do with the make up of the eye which is different in animals with much better night vision than humans - all very technical but involved with the retina & something called the tapetum lucidum which reflects light that has already passed through the retina back through the retina a second time, giving the light another chance to strike the light-sensitive rods.

Answer 2

Red eye is one of the most annoying things in photography.

It doesn't matter if you use film or digital cameras, results are the same, especially when photographing in dark places.

Red eye can be corrected with many computer programs, but there are steps that can be taken to avoid it from the beginning.

Red eye happens when the light from the camera's flash travels through the iris and bounces off the retina in the back of the eye.

This appears red in the image because of the blood, which acts as a mirror.

When photographing pets, their eyes often appear yellow, white or green.

Many of the new pocket digital cameras have settings to reduce red eye, but not all of them work.

This feature reduces the effect by sending out multiple flashes. The first comes before the image is taken, causing the pupils to contract; the second comes when the photo is taken.

Often, the subject's eyes close after the first light burst, and that's captured in the image.

To avoid red eye, don't photograph subjects looking directly into the flash.

With cameras that have built-in flash units, this can be difficult because when subjects look at the camera, they are also looking at the flash.

Consider photographing in profile, from farther away or without using the flash.

Many of the higher-end cameras accommodate an off-camera flash, which is a great way to avoid red eye. Position the flash away from the lens so the subject isn't looking directly at it.

If there is more light available, such as through a window, use it and not the flash.

Direct flash in a dark room almost guarantees red eye, so add the most nonflash light possible.

With the extra light, the subject's eyes might be smaller or narrower, reducing red eye.

The ISO settings do not have an effect on red eye as long as the flash is used.

Increasing this setting allows images to be taken in lower light conditions, reducing the need for flash.

If the flash must be used in a dark setting, zoom out as much as possible, which also reduces red eye.

If you choose to use the camera's red-eye-reduction setting, warn the subjects that they will see multiple flashes, in hopes of reducing the likelihood of their blinking.

Remember, this can reduce red eye, not eliminate it.

A great thing about digital cameras is the image can be checked on the display screen to be sure people's eyes are open.

And finally, remember red eye in digital images can be fixed with most photo-editing programs.

Chetco's answer is excellent and well researched. There is a theory amoungst Bernese Mountain Mountain Dogs people, that since the colour that dogs' eyes reflect is linked to pigmentation etc., those that reflect red most probably carry the gene for blue eyes whilst those that reflect green, to greenish/white do not. I am not aware of any conclusive studies undertaken, but certainly no blue eyes have ever resulted from parents that reflect green or if one parent reflects green, but blue eyes do occur if both parents reflect red.

Answer 4

Both of my dogs get red eyes too. It's the relection of the flash in the pupils of the eyes. It just depends on the color inside the pupil. Some dogs show orange, some cats glow yellow.

Answer 5

Sorry but whenever I take pics of my dogs they have red eyes.

Answer 6

red eye photography animals as well as humans has always been a nuisance and now it can be overcome with the digis so have a talk with the camera shop manager as to which digi you purchase
