Reverse Engineering of a Disposable Camera Jasmin Quevedo

The casing protects the camera from damage. It also contains information for selling purposes. It mainly prevents light from making contact with the film and it holds everything in place.

The shutter is a sealed box that does not allow light into into it. It opens and closes between the lens and the film. The shutter also controls how long the film is being exposed to light. When the shutter's release is clicked, the curtain slides open and exposes the film, it then closes again.

The lens is a curved piece of glass or plastic that redirects beams of light that bounce off and then come together to form an image.

The film is a light sensitive emulsion on a plastic base. The light reflected off goes through the cones through the lens and strikes the emulsion which is the part of the film that allows images to be recorded.

The flash circuit is the solution to dark indoor pictures. It allows clear pictures using electronic flashes which makes a bright light. The three main parts are the battery, the gas discharge tube and the electrical circuit.

The gas discharge tube is what actually produces the bright flash. It is a tube filled with xenon gas. It has electrodes on each end and a metal trigger plate in the middle hidden by a reflective material. This material directs the flash light forward. It conducts an electrical current which moves electrons causing them to energize xenon atoms and emit light making the flash.
