Exposure control refers to the methods and practices used to limit a person's exposure to harmful substances or environments. This is especially important in workplaces where employees might encounter hazardous materials, such as chemicals or radiation. By implementing safety measures, such as proper ventilation, protective equipment, and regular monitoring, organizations can help ensure the health and safety of their workers. In photography, exposure control is about managing the amount of light that reaches the camera sensor. This is achieved through adjusting settings like aperture, shutter speed, and ISO. By mastering these elements, photographers can create images with the desired brightness and clarity, capturing the perfect moment in any lighting condition.
