light exposure
Receiving radiant energy
Light exposure is the amount of light that reaches a surface, sensor, or living thing over time.
In photography, it determines how bright or dark an image appears: The photo was ruined by too much light exposure.
In health contexts, it refers to sunlight reaching the body, affecting vitamin D production, circadian rhythms, and skin damage risk: Limit your light exposure during peak UV hours.
