# data[].attributes.body
Partial Metering is a camera-metering mode in which the metering is weighted at the center of the viewfinder (unlike center-weighted in which the camera averages the exposure based on the reading at the center).

# data[].attributes.body
Centre-weighted Average metering is like using Evaluative metering with a centre AF point. It places greater emphasis on the centre area while also taking meter reading across the entire frame.
