Yes, It's the camera flash bouncing off the red blood vessels and red tissue in the back of our eye
Red-eye reduction in a camera works by emitting a pre-flash of light before taking the actual photo. This pre-flash causes the pupils to constrict, reducing the amount of light that reaches the back of the eye and minimizing the reflection of the camera flash off the blood vessels in the retina, which is what causes the red-eye effect in photographs.
The person in the photo has one red eye due to the camera flash reflecting off the back of their eye, which is a common occurrence in flash photography.
Achieving red eyes in photos is typically caused by the camera flash reflecting off the blood vessels in the back of the eye. This effect can be minimized by avoiding direct flash, using red-eye reduction settings on the camera, or editing the photo afterwards to correct the red-eye effect.
When wanting a quality image from a camera, professional photographers often use a flash bracket. The bracket has a flash that is not built directly in the camera and it keeps the images from having the red-eye effect.
The red eye effect in photos happens when the camera flash reflects off the blood vessels in the back of the eye. This is more common in animals with a reflective layer behind their retinas, like dogs. It's not harmful, but can be reduced by avoiding direct flash or using red-eye reduction settings on your camera.
Yes, red eye can indeed be eliminated with that camera.
Auto flash, Red Eye flash, and no flash
The "red " in the eyes of some people is from a camera with a FLASH. In the flash the person is in a dark setting so this makes their iris dilate letting in light from the flash. In the back of the human eye is a blood rich retina that turns focused light that hits it and turns the light into electrical signals that travels through optic nerve to the brain. The brain then turns these electrical signals into a arrangement (digital) that our brain understands as a image. I digress; the "red" eyes in the photo is due to the flash hitting the retina and is reflected back to the lens of the camera
It's caused by the reflection of the color of the Retina.... The retina is red so when the flash from a camera goes all the way to the back of the eye it some of it bounces back and reflects the color of the retina...
Red eyes occur when the flash reflects back to the camera from the blood vessels in the back of the eye. It is most common with blue-eyed subjects and children, but can occur in any situation where the pupils are dilated (the dark circle in the middle of the eye is wide open). It is caused by having the flash too close to the lens. Some cameras attempt to solve the problem by "pre-flashing" the flash to cause a reflexive dilation of the pupil. Sometimes this works; sometimes it doesn't. Reduce or eliminate it by increasing the surrounding light to cause the pupil to dilate (shrink), by using an off-camera flash, or by eliminating the flash entirely and shooting with a brace or tripod if the light cannot be increased. You can also ask your subjects to look at each other, or at some other point of interest, rather than looking at the camera. (This often results in more natural pictures, anyway.) The flash can also be deactivated on most digital cameras. Check your handbook. The camera will then compensate for the lack of flash. You can get some nice images that way if you are good at holding the camera steady.
"If an eye had absorbed all light, then this wouldn't happen. In fact, if an eye had been theoretically flawless, the red eye effect would not have existed at all. What happens when you see the red eyes on pictures, is that the flash is reflected in someone's eye. The reflection is red because of all the blood vessels inside the eye." -http://photocritic.org/red-eye-removal-reduction/
The red shine is due to light reflecting from the dog's retina, which is reddish brown due to the blood vessels. It is the same effect that gives people 'red eye' from the camera flash, in a photograph.
