Exposure refers to light being exposed to your camera’s image sensor. A long exposure means more light will reach your sensor, while a short exposure means less light will get in. In a long exposure situation, your image will be nice and bright, while a short exposure will make your image pretty dark. Long exposure is usually used as a cinematic tool for a specific effect.
