Key Topics to Revise

1

Working of a Camera

  • A camera is a light-tight box that allows controlled amounts of light to fall on a light-sensitive surface (film or digital sensor).
  • Too much light causes overexposure (image appears too bright), while too little light causes underexposure (image appears too dark).
  • Two main components control the amount of light entering the camera: the shutter and the aperture.
2

Parts of a Camera

  • Viewfinder: Used to look and aim the camera at the subject.
  • Shutter Release: Button pressed to take a photograph.
  • Lens: Most important part; focuses light onto the sensor/film using glass elements that bend light.
3

Properties of a Lens

  • Different lenses provide different angles of view and magnifications.
  • Wide-angle lens: Short focal length, captures a broad scene, makes subjects appear smaller.
  • Telephoto lens: Long focal length, brings distant subjects closer, narrows the field of view.
4

Other Important Equipment in Photography

  • Flash: Provides a burst of light during exposure, useful in low-light conditions or to fill shadows.
  • Built-in flashes are less powerful; external flashes offer more control and intensity.
  • Tripod: A three-legged stand that stabilizes the camera, especially important during long exposures.
