Photography is one of things that people think that it works by magic. There is no such thing as magic so in this assignment I will show how a camera works. The technology making up a camera is very basic. A simple disposable camera work in much of the same way as a $600 one. All cameras consists of three basic elements, an optical element (the lens), a chemical element (the film), and the technology element or rather the camera body. The only differences between expensive and cheap plastic cameras are their functions. The real hard part of producing a camera is the way they are assembled in such a fashion it is able to record beautiful pictures. The one I will be explaining is the SLR the manual single-lens-reflex camera, the camera that is used by professionals. It is rather older fashioned compared to the new point and shoot cameras but it includes all the fundamental processes of photography. The Science: The science in how a camera works is how it bends the light in other to allow it to be exposed on the film. This science -- bending light. Within the camera are many different parts but the one that bends the light or rather refract, is the convex/converging lens. A converging lens is the ones that have ends curving outwards. How does a simple piece of glass bend light? Easy, light travels faster in some substances than in other; so it travels faster through the air than glass. When the light hits the lens at an angle, the light will start to down while going through the glass. Because the light is travelling slower, the light bends towards the lens, and when the light leaves the lens it has a new course! Since it is bent inwards, the light is bent towards one spot, the focal point, it is where the object being photographed is flipped around, producing a real image. Of which is printed onto the film. Lens Since a lens can bend light, we can change the thickness of the lens to vary the bending angle.
