The Camera consists of a convex lens supported at one end of a light proof box and a light sensitive film at the other end. The distance between the lens and the film can be adjusted. There is a shutter behind the lens.
When we click our Camera, the shutter opens and the light from the object passes through the lens. The lens forms a real, diminished and inverted image on the film. A diaphragm of Variable aperture is also provided so that the amount of light entering the Camera can be controlled.
