Why does Xiaomi 3 front camera sometimes have whitening effect and sometimes not?

Why does Xiaomi 3 front camera sometimes have whitening effect and sometimes not? This problem actually involves some differences in technical principles and settings of mobile phone cameras. We need to know how the Xiaomi 3 front camera achieves whitening effect.

During the shooting process, the mobile phone camera will process the image according to the preset shooting parameters, including exposure, contrast, saturation and other settings. Whitening effect means that the camera adjusts the skin color in the process of image processing to make the skin look whiter. This function is realized by software algorithm, which simulates the perception and cognition of human eyes for skin color to some extent.

Why sometimes taking pictures will have whitening effect, and sometimes it won't? This is mainly due to the following reasons:

Different ambient light will affect the shooting effect. Under strong light, the camera will automatically reduce the exposure and increase the contrast, so that the photos taken will appear clearer and brighter, but it may also lead to darkening of skin color and loss of whitening effect. In low light environment, the camera will automatically increase the exposure and decrease the contrast, so that the photos taken will appear brighter and whiter.

The distance between the person and the camera will also affect the whitening effect. When people are far away from the lens, the camera will automatically increase the focus range, and the overall image processing will be more balanced, making the skin color of people in the photo more even and fair. When people are close to the camera, the camera may focus more on capturing people's details, which may weaken the whitening effect.

Different mobile phone manufacturers have different ways to deal with whitening effect. Some mobile phone cameras may turn on the beauty function by default, and even the front camera will automatically whiten, making the skin color of the characters look brighter. However, some mobile phones may not turn on the beauty function by default, and users need to manually set it or use third-party applications for beauty treatment.

Xiaomi 3 front camera sometimes has whitening effect, and sometimes it has no whitening effect, which mainly depends on the comprehensive influence of many factors such as ambient light, the distance between people and the lens, and the setting of mobile phone camera. If you want to shoot a whiter complexion, you can try shooting in a low light environment, adjust the exposure and contrast settings of the mobile phone camera, or use a third-party beauty application for processing. You can also shoot and post-process according to your own preferences and needs, and choose the whitening effect that suits you.
