What is a "light meter"?

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.

Light meters can be built into cameras or used as separate handheld devices.
