A Camera
The invention of the camera has made it possible for mankind to store memories for posterity. Through it, man can freeze a moment in time forever. Unlike yesteryears, the camera of today is a small and portable instrument. It can be slung on the shoulder or hung around the neck. It can also be mounted on a tripod for greater stability of the picture. It has a rectangular cubic structure. The front portion is occupied by the lens and its fitments. The focus ring is mounted on the top of the circular lens. Provisions are also made for the mounting of additional lenses on the circular lens. On the top of the camera are the shutter button and a lever that helps a person roll the film inside the camera once a frame is exposed. In between, them is a provision to fit the flashlight/gun. At the back of the camera is a door, through which a roll of film can be inserted inside a camera. In order to take a photo, a person has to aim the camera at the object that is to be photographed. He has then to focus the object properly. Then he has to press the shutter button. The film inside the camera gets exposed to the light that enters the camera through the lens aperture. In this way, a negative photograph of the object is obtained.
