The light metering modes of DSLR or Mirrorless cameras, such as matrix mode, are used for photometry, not for focusing. Photometry is the measurement of the light that enters the camera, and matrix mode (also known as matrix metering or standard metering) evaluates the brightness in several areas of the scene to determine the correct exposure. It takes into account the overall lighting, contrasts and even the color and composition of the scene to provide a balanced exposure. Spot metering, unlike matrix metering, considers only a small central area (or a specific selected area) of the frame, usually about 1-5% of the total scene. This area is often indicated by a dot or small circle in the viewfinder, and is a very accurate measurement that is useful in high-contrast situations where there is a large variation in light in the scene. For example, when photographing a subject against a very bright or very dark background, spot metering allows you to correctly expose the main subject without being influenced by the background. For focusing, DSLR cameras use different autofocus modes, such as single-point, zone, and continuous autofocus, but these are distinct from the light metering mode. Confusion between focus and metering modes is common among beginners in photography for several reasons, such as: Similar Technical Terms: Many technical terms used in photography may sound similar or be used in overlapping contexts, such as “matrix mode”, “autofocus”, and “exposure”. Camera Complexity: DSLR and mirrorless cameras have many adjustments and settings, which can be overwhelming for beginners. Focus mode, metering mode, ISO, aperture, and shutter speed are just a few of the many parameters that need to be understood. Ambiguous or Incomplete Information: Information found in tutorials or manuals may be difficult to understand or may explain complex concepts in a simplified manner, leading to misinterpretations. Practical Learning: Many beginning photographers learn through trial and error, which can lead to confusion. For example, they may change a setting that influences photometry thinking they are adjusting focus, or vice versa. Different Equipment: Different brands and models of cameras have different systems and terminologies, which can further confuse. What is called “matrix mode” in one brand may have a different name in another. To overcome this confusion, it is useful to study the fundamentals of photography, read the camera manual carefully, and practice a lot. Participating in courses or workshops can also help clarify these concepts in a practical and interactive way. Att: Roberto Dellano ===============================================
