Why am I the only one with red eyes when taking pictures?

Red eyes have nothing to do with your myopia.

Large pupils do not mean that the eyes are too big.

The human eye is in a darker environment.

When you suddenly encounter a bright light.

The pupils dilate to adapt.

When you encounter the flash of the camera, you will be refracted by the reflection and retina of the light.

Anyway, if you can't tell, you'll have red eyes.

Ways to avoid red eyes.

In fact, it is to avoid encountering a flash when the pupils are dilated.

1. You can turn on the flash first when taking pictures.

Adjust your pupils to the bright light of the flash.

Then shoot normally.

2. If it's too late.

You can make the person with the camera stand farther away.

It might be better to distance yourself from the camera.

Meantime. Don't keep your eyes glued to the camera and flash.

You can look at the person's hand or a little further away.

Normal physiological responses.

As a friend upstairs posted.

Red eye is a reaction of blood vessels, everyone's physiological characteristics are different, maybe you are more sensitive, just like most people are not allergic to pollen, and some people can't stand it.

In fact, you yourself describe the cause of the problem.

2. Since you are myopic astigmatism, when looking at the lens, your eyes are not as accurate as others can focus on the lens, so the anti-red eye pre-flash response is not so sensitive (it can be described as you are not as clear as others to see the flash), so the pupil constriction response is not as strong as others.

As a result, you're red-eyed and a lot of people aren't. Knowing this, you know what to do, don't worry, it's even less likely to be red-eyed, haha.

At the same time, don't keep your eyes glued to the camera and flash.

Don't be nervous every time, maybe it's psychological tension that causes the pupils of your eyes to contract or something.

Red eyes have nothing to do with myopia.

Red eye is the color of blood vessels reflected by bright light shining on the retina.

It is estimated that the shooting is not in the red-eye mode, usually in the flash mode there is a pattern of glasses.

The principle of this mode is to pre-flash a few flashes or turn on strong lighting, so that the pupil is narrowed, so that the retina of the glasses receives more burning light and cannot see the red eye clearly.

You can also flash off-camera, if it is a DSLR, you can use a sync cable to flash the flash out of the camera, so that the light will not shine on the retina, and there will be no red eye at all.

You can also use a jump lamp, that is, to shine the lamp to the ceiling and use the reflected light to shoot, which is similar to the effect of leaving the machine, and there will be no red eye.

If you want to fix the red eye that has appeared, you can only rely on software, as said upstairs, PS and other professional ** repair software have this function.

Hehe, don't keep your eyes on the camera the next time you pay attention to the camera!

And even if you have red eye, it's okay.,Use access or photoshop to remove red eye.,You can also send me **,I'll help you remove it! It's mine.

It may be that you are the only one who inadvertently looked at the flash when taking pictures, and you can put ** on the PS3 to fix it yourself, or you can adjust the camera to the anti-red-eye function.

Congratulations, you're the legendary berserker haha.

It seems to be a problem with your elderly eyes. The capillaries in the eye are more developed. Don't look at the flash, it may be better to keep it at an angle.

The "red eye" phenomenon occurs because the flash axis of the flash is too close to the optical axis of the lens, and the light is very dark outside.

When the flash of the flash shines through the pupil under the fundus, the dense capillaries are reflected back by the bright red color under the light, and the natural phenomenon of "red dots" on the eyes is "red eyes".

Nowadays, many DCs and FCs are designed to be light, short, and portable, so it makes sense that the flash is closer to the lens. I believe you have seen the built-in flash of a "point-and-shoot" camera right next to the lens, and even if the "top light" of a DSLR camera can "jump", it is still not far from the lens. In short, as long as the angle between the lens and the flash is too small, it is easy to form an annoying "red eye" phenomenon.

In response to this "red eye" phenomenon, many digital cameras have also made corresponding "countermeasures". Generally, the "red eye" elimination function of digital cameras is mainly through the pre-flash of the flash, which causes the pupil to contract to a certain extent to reduce the reflected red light. Although this method can effectively reduce the "red eye" phenomenon, it is actually extremely limited, and does not really completely eliminate or avoid the occurrence of "red eye" phenomenon.

In addition to pre-flashing the camera flash or making some technical improvements, the more effective way to avoid the "red eye" phenomenon is to use diffused light, let the flash do some degree of refraction (shining on the ceiling, and then refracting on the portrait), or use an external flash to increase the distance between the lens and the flash, which can effectively eliminate the red eye.

Red eyes mean that the eyes of the people on the ** are red, and they are not as good-looking as the free children

Red eyes are actually blood vessels in the human retina, and light is reflected into the camera

The function in the camera is red-eye proof.

Red eyes are produced when the flash of an electronic flash hits the retina and reflects back to the camera lens. Red eye can easily be caused when the light is very close to the lens, such as with a camera with a built-in flash. Some cameras have a red-eye reduction feature that can reduce red-eye in many cases, but it doesn't solve the problem at all.

There are some precautions that can help reduce the phenomenon that causes red eyes, but it is not possible to completely eliminate red eyes in all cases. The degree of this phenomenon varies widely and is influenced by a combination of factors, including the characteristics of the subject's eyes, the distance between the flash and the lens, and the intensity of the existing (ambient) light. Because of these variables, even if you use the same camera to shoot the same object, you are likely to have a red eye in one situation and not in another.

We found that in some group photos, some people had red eyes and others did not. It is important to note that children are more likely to have red eyes than adults, mainly because their pupils do not respond to light as quickly as adults. The following techniques can help reduce the appearance of red eyes.

Increase the brightness of the environment before shooting. This causes the pupils to narrow, so the red eye becomes less noticeable (which is why red eyes rarely occur when taking photos with flash outdoors). Shooting less than five feet away can also help reduce red-eye.

Because this increases the angle of reflection (from the flash to the lens), it is likely to reduce red-eye. If you can, ask the subject to look at the light source for a while before taking the photo. This will also shrink the eyeball.

The flash of many cameras has the option of anti-red eye, otherwise use a high point sensitivity, do not turn on the flash, if you are a DSLR, it is better to use an external flash, change the angle of the light, do not flash at the face.

Don't use flash, choose to take photos in a well-lit place. If you can't find a place with good light, then use the anti-red eye function of the digital camera, at this time, the camera will flash twice, the first time to let the eyes of the person being photographed adjust to the flash, and the second flash is the official shooting.
