Digital cameras work out the correct exposure by measuring the light levels across the scene you’re photographing. But they can split the scene up in different ways to make these measurements, using different metering patterns, or metering modes. By default, cameras analyse the scene by splitting it up into segments. This is called ‘multi-segment’ or […]
Digital cameras usually use multi-pattern/multi-segment light metering, but they also offer other 'metering modes' – centre-weighted metering (simpler) and spot metering (more precise). The camera will have a button or a menu option for changing the metering mode.
