How to choose the metering mode correctly in the setting of mobile phone photo video APP?

Hello! The metering choice of Xiaomi mobile phone camera is based on your needs.

1. Average photometry is to measure the average brightness value of the whole picture, and take the result as the calculation basis of exposure.

2. Center metering should be pointing metering, that is, measuring a small percentage (such as 3%, 5%) of the center of the picture. This has the advantage that the object in the picture can be accurately measured. The area percentage may have different values for each manufacturer and each model of each manufacturer.

3. Center photometry, probably about the average photometry of the center key, is based on the area of the center of the picture as a certain proportion, and then calculated with the result of average photometry of a certain proportion, taking the calculation result as the exposure basis. In this way, the sum ratio and calculation ratio of different manufacturers are different, and each model may need to be adapted for users.

I hope I can help you!
