What does overexposure mean?
Overexposure is the condition of receiving too much of something that can affect a person, object, or event. The most familiar meaning is photographic: when a camera allows too much light onto the film or digital sensor, the resulting image appears excessively bright and may lose detail, especially in highlights. The term can also describe excessive exposure to radiation, chemicals, sunlight, information, or public attention. In health and safety contexts, overexposure often suggests a potentially harmful amount of contact. Figuratively, it may indicate that a person or event has received an excessive amount of media coverage, sometimes with the implication that attention has become excessive or distorted. The word is most common in British and American English and is especially frequent in technical, scientific, journalistic, and media-related contexts.
