Getting to Know Your Camera

  • Camera - a device that records images that can be stored directly, transmitted to another location, or both. These images may be still photographs or moving images such as videos or movies. The term camera comes from the word camera obscura (Latin for "dark chamber").
  • Camera Lens - an optical lens or assembly of lenses of different focal lengths used in conjunction with a camera body and mechanism to make images of objects.
  • Camera Body- the light-tight primary portion of a camera, which contains the controls, light-sensitive film or digital sensor, viewfinder or LCD, and any associated circuitry.
  • Aperture – a hole or an opening through which light travels. More specifically, the aperture of a camera is the opening that determines the cone angle of light that comes to a focus inside the camera body.
  • Shutter – a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture an image.
