ABSTRACT
Photography is highly dependent on equipment. All photographers utilize devices, often in the form of a camera, to make images. A camera is essential for producing photographs. A photographer’s camera is a tool, just like a violinist’s violin, a tennis player’s racket, or a Jedi knight’s lightsaber. The lens of the camera takes in rays of light that have reflected off the subject being photographed. Camera lenses are capable of refracting, or changing the direction of, these light rays so that the rays coming from a single spot on the subject meet again at a certain distance on the other side of the lens, forming an image of the subject. Single lens reflex is a camera body type. The name comes from its structure: one single lens is used both for viewing the image before the shutter release is pressed and for capturing the image when the shutter release is pressed.
