How to measure light with mobile phone?
In the mobile phone metering mode, select the metering mode and click the average metering, which is equivalent to dividing the picture into many cells, obtaining a sidelight value for each cell and then taking the average value. Average photometry is suitable for scenes with uniform light, such as landscapes and buildings. In these two modes, there are a lot of picture details to take care of, so average metering is a more common mode.

Some mobile phone photometry is called central focus photometry, central photometry or multiple photometry, which is characterized by focusing on the central part of the picture, and the photometric area accounts for about 10% of the picture. This is suitable for shooting scenes with prominent themes, such as still life, environmental portraits, food and other themes.
Some mobile phone metering is called spot metering, and its metering area is about 2% of the whole picture, which is located in the center of the picture and is more suitable for larger scenes. When the subject is in sharp contrast with the ambient light and needs to be focused, spot metering can be used, and only a certain part of the subject needs to be measured. Spot metering is often used in the metering mode of SLR cameras.
