Glossary Of Photography Terms [1]

Light Meter A light meter is a device used to measure the intensity of light in a scene, typically expressed in units such as lux, foot-candles, or exposure values (EV). Light meters are essential tools for photographers and cinematographers to determine proper exposure settings, including aperture, shutter speed, and ISO sensitivity, based on the available light levels and desired creative effect. Light meters may be built into cameras as integrated light metering systems or external handheld devices that measure incident light or reflected light from the subject.

Incident light meters measure the light falling on the subject, while reflected light meters measure the light reflecting off the subject or scene. Light meters provide accurate exposure readings and help photographers achieve correct exposure and optimal image quality in various lighting conditions, including natural light, studio lighting, and mixed lighting environments.
