Why does the mirror look good on you and the lens looks ugly?

You have to believe that looking at yourself in the mirror is the truest! No camera can achieve the same authenticity. If the mirror looks good, it means you look good, but your image is slightly distorted by the lens. \x0d\\x0d\ One more thing: What you see in the mirror is a real 3D image without distortion, while what the camera takes is basically a planar 2D image. Just like you have the opportunity to go to the Grand Theatre to listen to a live concert and then go home to listen to the same performance on the stereo, it is impossible to achieve the same real effect on the spot anyway. At most, the advanced sound is closer to the scene. Modern digital cameras only capture light through the lens, then convert it into electrical signals through photosensitive elements, and finally generate digital images. Even the most advanced photosensitive elements and lenses can't achieve the effect of human eyes and can't restore the real effect like a mirror. Technically speaking, the imaging latitude of photosensitive elements is far from that of human eyes, and even the most advanced lens will be distorted. The color reproduction accuracy of any camera is not 100%. \ x0d \ x0d \ However, on the other hand, the photos taken by digital cameras have room for adjustment and modification. As long as the camera itself has a good image, it can achieve satisfactory results and even beautify the real effect by making necessary modifications through the later software. This is why countless people pay photographers to take pictures of themselves! A photo may never be as real as a mirror, but it can be more beautiful than a real photo. \x0d\\x0d\ If you want to take photos as beautiful as yourself or more beautiful than yourself, you can choose professional photographic equipment, learn to adjust posture and angle, learn to decorate the outline with light or natural light, or post-process the photos with PS, so that the photos can be beautiful.
