A camera has three essential components: the aperture at the front, a lens in the middle, and a film at the back. When you take a photograph, the aperture opens briefly letting light rays pass through the lens and onto the film inscribing an image. One can modulate the focus by adjusting the distance between the three components. The apparatus imposes limits on how far and how close one can focus. Beyond these limits the image gets severely distorted.
