DIGITAL PHOTOGRAPHY TASK 1 * APERTURE -A n   aperture   is a hole or an opening through which  light  travels. More specifically, the aperture of an   optical system is the opening that determines the cone angle of a bundle of  rays  that come to a  focus  in the  image plane . The aperture determines how  collimated  the admitted rays are, which is of great importance for the appearance at the image plane.  If an aperture is narrow, then highly collimated rays are admitted, resulting in a sharp focus at the image plane. If an aperture is wide, then uncollimated rays are admitted, resulting in a sharp focus only for rays with a certain focal length. This means that a wide aperture results in an image that is sharp around what the lens is focusing on and blurred otherwise. The aperture also determines how many of the incoming rays are actually admitted ('allowed into') and thus how much light reaches the image plane (the narrower the aperture, the darker the image for
