The video camera is made up of two elements, the optics and the electronics. The optics section collects the light from the scene being photographed and focus it into a clear image. The electronics turn that image into electrical signals which can be recorded onto magnetic tape, disc, etc. The camera use a lens to focus the light, and virtually all video cameras use a zoom lens. This enable the camera to record many shots from a wide panoramic view to a tight close up without changing the lens. The light passes through an iris, a hole that automatically alters in size to ensure that the brightness of the image is correct. It's mean teh picture is not over or under exposed. Some cameras have a manual iris which can be adjusted. Bringing the picture into sharp focus, can be done manually or automatically. The final image is projected onto the camera pick up image called CCD or Charge Couple Device. This is the section where the electronic start. The CCD turns the image into electrical signals. The video camera also has a viewfinder. This viewfinder allows the cameraman to see what the camera lens is seeing. Video camera is also fitted with a microphone to record the sound.
