Light metering is the process of measuring the amount of light in a scene to determine the correct exposure settings for a camera. This helps photographers capture images that are neither too bright nor too dark. Light meters can be built into cameras or used as separate devices, and they assess the light conditions to suggest optimal aperture, shutter speed, and ISO settings. There are different types of light metering modes, such as spot metering, center-weighted metering, and matrix metering. Each mode evaluates light differently, allowing photographers to choose the best method for their specific shooting conditions. Understanding light metering is essential for achieving well-exposed photographs.
