METERING MODES
EVALUATIVE
1The Evaluative metering mode, also called Multi-Zone or Matrix, is the default metering mode that is suitable for most everyday scenarios. This mode takes into consideration exposure information across the whole scene, though will put some bias towards your autofocus point (or points) to make sure that your subject is decently exposed. By and large, this is the metering mode you should stick to for the majority of your shooting until you nd that you need to force the camera to over- or under-expose.
CENTRE-WEIGHTED
2This mode is similar to Evaluative mode, in that the camera will take into consideration a large portion of the scene on which to base its exposure settings. The key dierence is CentreWeighted Average will bias more to the middle of the frame, so any extremely bright or dark areas around the edges won’t be taken into consideration. While this is useful in a handful of situations, it’s sometimes easier to shoot in Evaluative mode and adjust the exposure with exposure compensation.
SPOT METERING
3Spot metering typically only reads data from a very small portion of the frame, about one to four per cent, and is ideal for basing your metering around a small point in your shot that you’d like to be perfectly exposed. Typically the ‘spot’ area is based on the central autofocus point, though many modern mirrorless cameras allow you to tap the screen to place the spot metering point exactly where you want it in the scene, separate from the active autofocus point. This is often used in wildlife photography.
