Definition of Term

  • The device on a camera that opens and allows light to pass to the sensor or film for a set period of time in order make an exposure



  • Shutter speed exists because of something known as your camera shutter – which, simply put, is a curtain in front of the camera sensor that stays closed until the camera fires. When the camera fires, the shutter opens and fully exposes the camera sensor to the light that has passed through your lens. After the sensor is done collecting the light, the shutter closes immediately, stopping the light from hitting the sensor. The button that fires the camera is also called “shutter” or “shutter button,” because it triggers the shutter to open and close.
