تعریف و معنای "exposure"

What is "exposure"?

Exposure in photography refers to the amount of light that reaches the camera’s sensor or film, determining how bright or dark an image will appear. It is controlled by three main settings: aperture, which is the size of the lens opening, shutter speed, which is how long the camera's shutter stays open, and ISO, which is the sensitivity of the sensor or film to light. Proper exposure ensures that the details in the highlights and shadows are well-captured, resulting in a balanced and clear image.

What is "exposure"?

Exposure is a serious medical condition that occurs when someone is outside in extremely severe weather conditions for a prolonged period without protection from the harsh elements. This can lead to significant health risks, including hypothermia, when the body loses heat faster than it can produce it; frostbite, which is damage to skin and tissues due to freezing; and heatstroke, when the body overheats. Symptoms of exposure can vary depending on the weather conditions but may include shivering, confusion, numbness, weakness, and loss of consciousness. It is essential to seek shelter and warm up or cool down as soon as possible to prevent further complications and seek medical attention if symptoms worsen.
