Why is there a huge difference between human eye illumination and camera illumination?

The structure of the human eye and the camera is completely different, so the imaging state is also different, so the scenery seen by the human eye is very different from that taken by the camera. This is normal, not surprising at all. As for the effect of the camera shooting light photos, it is not all chaotic and turbid, but also clear and sharp. This has something to do with photography.

For example, in this photo, the light is clear and not turbid.

For example, this photo is clearer and definitely not turbid.

In fact, it is really not easy for the camera to take photos of the lights. You must choose the right aperture to take a photo of light that is neither dazzling nor turbid.

Even sometimes, the camera can take a starlight effect (under a very small aperture). This effect is really beautiful, but it is invisible to the human eye ... This is the most obvious example of the difference between the human eye imaging effect and the camera imaging effect.

As for the difference between the imaging effect of the human eye and the camera, we should not only understand the physiological knowledge, but also the optical knowledge, and also understand the imaging principle of the camera ... Most people don't have this ability. We can only have a general understanding of ... ...

The visual angle of the human eye is similar to the focal length of a full-length camera of about 50 mm, which is why this lens is called portrait head ... not only because it is suitable for taking portraits, but also because the imaging effect of this lens is close to the visual angle of the human eye, which makes it most comfortable to watch. ...

One more thing ... the photos taken by the camera are confusing and turbid, which may be caused by the shooting technology or the equipment itself ... especially the camera of the mobile phone, because it is often put in the pocket, the camera lens is easily polluted. At this time, if you take pictures of the lights, you will feel turbid. ...
