Which is real, the mirror or the camera?

The self in the mirror and the self in the lens will be deviated because of the cognition of the human brain and other reasons, and it is not the real self.

Considering physical optics and the physiological structure of human body. People's pupil aperture and focal length are far from the front camera of mobile phone. The imaging structure is completely different. People's glasses are said to have 500 million pixels, while the highest camera of mobile phone does not exceed 1 100 million. People's glasses are imaged as eyes, and there is basically only one front camera for mobile phones.

From the imaging principle, looking in the mirror is relatively closer to reality. Because looking directly in the mirror follows the principle of light reflection and forms a virtual image with opposite left and right in the mirror, you are seen symmetrically in the mirror, but people will have subconscious psychological hints when looking in the mirror. In order to make themselves look better, they will adjust the angle, expression and distance of looking in the mirror, and gradually understand the best angle and state of looking in the mirror, which is also the reason why he often takes selfies.

From a psychological point of view, when you look at yourself in the mirror, your brain will automatically filter out some bad details for your beauty, so you should look 30% better than your real self, which means that this is actually a psychological hint. Robert Zajonk said, it's not that you are not photogenic, but that what you think is beautiful is actually beautifying yourself in the back of your head. He also put forward the "repeated exposure effect". When a person, an object or a thing appears in front of him repeatedly, his goodwill will continue to increase.

For those narcissistic friends, it is essential to look in the mirror every day, even dozens of times a day. Therefore, some girls like to look in the mirror for a reason. But what girls usually don't know is that they may not be real in the mirror, but they may be divorced from the real side, which is often what girls who love beauty yearn for.

Then, we explain from a practical point of view that there are many factors. The shape, aspect ratio and coating amount of the mirror will all affect what we see in the mirror. Take the mirror in the shopping mall as an example. People often look tall in this mirror because of the above factors. The reflection of light will make people's skin look smoother and remove fine lines and acne, while some people with good foundation will really look better in the mirror.
