Spontaneously capture life's precious moments with a disposable camera.
Disposable cameras are handy, inexpensively made cameras pre-filled with a roll of film and powered by batteries. They contain free-focus lenses, making them ideal for amateur photographers. Though many people consider their disposable cameras to be single-use devices, most are recycled by the film developer and returned to the manufacturer to be cleaned and used again.
Shell
The innards of a disposable camera are encased in a waterproof, molded plastic shell. The shell is made from opaque material to ensure that light cannot penetrate the casing and expose the film. The shell is self-sealing, the two sides fitting together and held by a series of strong clips inside the structure. It also contains a metallic coating where the edges meet to reflect X-rays and protect the film.
Internal Mechanism
When you press the button at the top of the camera to take a photo, you activate an internal mechanism that exposes the film to the image seen through the lens. The image is stored on the film, and a winding mechanism in the camera winds the film, moving the exposed film away from the lens and shifting new, blank film into its place. Some models lack a self-winding mechanism; the user must wind the film using a serrated wheel under the shutter button.
Electrical Components
The flash in a disposable camera is powered by a battery pack in the shell. When you turn the camera on, the battery charges a large capacitor to provide the flash with enough volts of power to operate. The flash will shine as you take the photo, to provide the frame with enough light. Because the shutter closes so quickly, photos need a lot of light at the time of image capture to display a clear image. After the image is captured, the capacitor loses its charge.
Film
Disposable cameras contain a roll of 35mm film. They are pre-filled, meaning that you do not need to wind or adjust the film before use. As the film is exposed to light when you take a photo, the exposure creates a chemical change on the film's surface, recording the image. The winding mechanism then pulls the film along to the opposite side of the camera, usually back into the canister, to ensure that the frame is not exposed to another image.
