Photometry is the science of measuring visible light, particularly the intensity of light as perceived by the human eye. It involves quantifying light in terms of its brightness and color, using specific units such as lumens for luminous flux and lux for illuminance. Photometry is essential in various fields, including lighting design, Photography, and vision science, to ensure optimal lighting conditions and visual performance.
