A light meter is a device used in photography to measure the amount of light in a scene. It helps photographers determine the correct camera settings, such as aperture, shutter speed, and ISO, to achieve proper exposure. By accurately measuring the light levels, a light meter ensures that photos are neither too bright nor too dark, resulting in well-balanced images. Light meters can be built into cameras or used as separate handheld devices.
