The original camera is different from all kinds of beauty cameras popular on the market now. The face shot by beauty camera has been automatically processed by software, and the face and facial features have been beautified. The most common functions are automatic face-lifting, automatic eye enlargement, automatic exfoliation and whitening. The characters under the lens of the original camera show the truest side, and the flaws on their faces are exposed under the lens. However, due to the wide-angle problem of the mobile phone camera, the characters usually shot are distorted, so most mobile phone users are reluctant to shoot with the original camera that comes with their mobile phones, and the faces shot are usually unacceptable to ordinary people.
