What is Matrix Metering

Matrix metering is a type of exposure metering system used by digital cameras to measure the brightness of a scene. It works by dividing the frame into several zones or segments and then analyzing each zone for its luminance, contrast, colour, and distance from the camera. Based on this information, the camera calculates the optimal exposure settings for the whole scene, taking into account the different lighting conditions and the main subject of the photo.

Matrix metering is also known as evaluative metering, multi-segment metering, or honeycomb metering. It is one of the most advanced and accurate metering modes available, as it can handle complex and dynamic scenes with ease. However, it is not infallible, and sometimes it can be fooled by very bright or dark areas in the frame, such as the sun or a black background. In such cases, you may need to use exposure compensation or switch to a different metering mode, such as spot or centre-weighted metering.


Matrix metering is usually the default metering mode on most cameras, and it is suitable for most situations. However, you should always check your histogram and preview your images to make sure that the exposure is correct and that there are no blown highlights or clipped shadows. If you want to have more control over the exposure, you can also use manual mode or aperture priority mode, and adjust the settings according to your creative vision and preferences.
