Why is it so ugly to take pictures with a rear camera?

1, camera and eyes may see differently.

Because for the camera, light, mirror, lens distortion and other factors will affect the final imaging effect, coupled with the different skills of the operator, it is difficult to get a static photo close to the real face.

2. The equivalent focal length of the mobile phone camera is very short, which causes the lens imaging distortion. Although it is necessary to add distortion control in the process of mobile phone optimization, this control is very limited. Different scenarios identified by software will lead to different control schemes.

3. The camera behind the mobile phone is generally suitable for shooting distant scenes. According to the perspective principle of the software, some optimizations are made. When shooting a portrait at close range, the software failed to identify the scene, which led to the optimization of the algorithm according to the distant scene and made the face look a little distorted.

4. In terms of self-timer, the front camera is much better. By changing the focal length of the front camera, it is more suitable for self-timer, the optimization difficulty is lower, and there are fewer scenes to be recognized. In addition, the pixels are lower than the rear camera, and the CPU processing efficiency is higher. Therefore, there is a specialization in the industry, and the task of taking selfies is still handed over to the front camera to work.

Extended data:

Looking in the mirror is better than the photos taken by the rear camera for the following reasons:

In psychology, there is an interesting phenomenon called brain tonic phenomenon. To put it simply, people subconsciously prefer to believe and enlarge their "good" side, and will automatically make "brain supplement" corrections to some shortcomings. This is also reflected in the fact that when looking in the mirror, the brain will automatically enlarge the advantages of the five senses and dilute the shortcomings of appearance.

People are dynamic when looking in the mirror, and it is often easier to show their best side in the mirror. Because what people see in the mirror will appear more real and three-dimensional, compared with photos, the dynamic you in the mirror are closer to what others really look like. However, due to the "brain-nourishing effect", many people just don't look as good as they think.

In addition, if you think you are ugly in the photo, don't lose heart at all, because there is a high probability that it is not true. After all, there are too many factors that affect camera imaging. In addition to taking "black photos" and "ugly photos" of normal people, some people take beautiful photos, and they are not necessarily really beautiful themselves.
