Exposures refer to the amount of time or intensity that an individual or object is subjected to a particular condition, such as light, radiation, or chemicals. In photography, exposure determines how much light reaches the camera sensor, affecting the brightness and clarity of an image. Proper exposure is crucial for capturing high-quality photographs. In health and safety contexts, exposures can relate to the potential contact with harmful substances or environments. For example, workers in industries like construction or manufacturing may face exposures to toxic chemicals or hazardous materials, which can impact their health over time. Monitoring and managing these exposures is essential for ensuring safety.
