Product Description

Video and lesson investigations on the topic of cameras . Key concepts include:

  • A camera is a device that makes a ‘picture’ form on a screen.
  • The key parts are a small hole to let light in and a screen where the picture (or image) can form.
  • A pinhole camera does not give a permanent image (photograph).
  • The screen needs to be translucent so that the image can be viewed from the opposite side of the screen.
  • The image will always be upside-down.
  • Turning the camera upside-down will not bring the image the right way up. In most modern cameras, the shutter setting and the focus are automatically controlled.
  • In the pinhole camera the ‘shutter’ (the pinhole) is permanently open and there is no lens to focus.
  • To get a clear image on the screen it is necessary to move the screen manually back and forth to bring the image into view.
