Sign in to savescience of the measurement of light in terms of perceived brightness
Photometry is the science of measuring light based on how bright it appears to human eyes. It matters because it allows us to quantify and understand the brightness of light in practical, human-relevant terms.

Photopic (daytime-adapted, black curve) and scotopic (darkness-adapted, green curve) luminosity functions. The photopic includes the CIE 1931 standard (solid), the Judd-Vos 1978 modified data (dashed), and the Sharpe, Stockman, Jagla & Jägle 2005 data (dotted). The horizontal axis is wavelength in nm.
Photometry is a branch of optics that deals with measuring light in terms of its perceived brightness to the human eye. It is concerned with quantifying the amount of light that is emitted, reflected, transmitted, or received by an object or a system.
