This is the casing. The casing protects the parts inside the camera from being damaged. It also protects the film from exposure to light.
The shutter is part of this section of the camera. It opens and closes between the lens and the film when a picture is taken. It controls how long the film is exposed to light.
The lens is a curved piece of glass or plastic. It's job is to redirect the beams as light bouncing off the object so that they come together and form an image.
This is the film. The film is light sensitive emulsion. When a picture is taken, the light hits the emulsion which allows the image to form.
The flash circuit helps get a clearer picture. There are 3 parts of the flash circuit; battery, gas circuit and electrical circuit.
The gas discharge tube produces the flash in the camera. It contains xenon gas (neon light). It also has electrodes on each end.
