Exposure
camera exposure determines how bright and dark the image will be after you take your picture, this is determined by 3 camera settings: ISO, aperture and shutter speed. A camera’s shutter speed is determined when the sensors of the camera will be open or close to the light coming from the camera lens. The shutter speed specifically refers to how long this light is going into the camera for. A camera’s aperture setting controls the area over which light can pass into the camera lens. It is specified in terms of a f-stop value, which sometimes can be counterintuitive, due to the area of the opening increases as the f-stop decreases.
