Why do I have red eyes when taking photos?

This is because the brightness of the camera is relatively high when it is **, so there will be a red eye phenomenon.

Because the ** degree is not adjusted well when taking pictures, it may cause red eyes.

When it belongs to the camera, I didn't master the technology, resulting in red eyes, and taking pictures is relatively high-tech.

It was possible that there was a problem with the camera, and there was also a problem with the light at the time.

It is usually caused by improper use of lights and cameras when taking pictures.

It could be because of the light or because of the camera.

This situation usually occurs when taking pictures, not physical reasons.

**The degree is not adjusted well, so it may cause red eyes.

in the camera"Red eyes"Explanation:

1.in the camera"Red eyes"The phenomenon occurs due to the fact that the flash axis of the flash is too close to the optical axis of the lens;

2.When the flash of the flash shines through the pupil under the fundus of the eye, 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 eye".

in the camera"Red eyes"A detailed explanation:

1.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.

2.Everyone has 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 lack of combustion of 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.

3.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 prompts the pupil to shrink the hole to a certain extent to reduce the red light reflected back.

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.

4.In addition to the pre-flashing of the camera flash or some technical improvements, the more effective way to avoid the "red eye" phenomenon is to use diffused light, so that the flash can be refracted to a certain extent (shining on the ceiling and then refracting on the portrait), or using an external flash to increase the distance between the lens and the flash, which can effectively eliminate the red eye.

It is because when people are in a dark environment, their pupils will unconsciously dilate, and when taking pictures, the flash will cause the blood vessels in the fundus of people's eyes to be reflected in the camera, and they will become red spots.

People sometimes have red eyes, and the red color in the eyes is due to the red spots of light produced by the camera's flash shining on the eyeballs, which are produced by the camera's light.

People sometimes have red eyes, and the red in the eyes comes from the person's eyes, because the pupils of the person's eyes are larger when they are in a dark place.
