Flash Circuit: What causes the flash mechanism. The flash helps light up the room so that the light can reflect off the object and be recorded into a picture.
Casing: The outer shell that surrounds the camera and protects the parts inside from being damaged. It also holds all the parts in place and prevents the light from contacting the film.
Lens: Redirects beams of light that are bounced off objects to form images
Shutter: A door that opens and closes between the lens and the film. When you take a picture, it opens and controls how much of the film is exposed to light.
Film: A light sensitive emulsion on a plastic base. When pictures are taken, the light reflects off the object into the lens and strikes the emission to record the image.
Gas Discharge Tube: A tube filled with xenon gas. It has electrodes on each end and a metal trigger plate. The trigger plate is hidden by a reflective material which directs the flash forward.
