A conventional camera has three elements to make it work. The optical element or lens, the chemical element or film, and the mechanical element or the camera body itself. Here are the basic parts of a conventional camera and its functions:
• The lens – It is a curved piece of glass or plastic that takes the beams of light bouncing off an object and redirects them to the camera operator’s eye.
• The film – Its job is to record the image the camera operator sees by chemically recording the pattern of light from the image. A film has a collection of tiny light-sensitive grains that record the light by chemically reacting to it.
• The camera body – Basically, exposing light to the film is not enough to get a picture. The film also needs to be protected from being exposed too long to light. A camera is a sealed box with shutter between the lens and the film; the shutter controls the amount light that comes in through the lens.
Too much light exposed to the film means the picture will look completely washed out, and not enough light exposed to the film will produce photos that are too dark. A conventional camera also has a part called a diaphragm and a shutter speed the photographer can control.
