Introduction to Camera Work Warm Up Preliminary Exercise 6


     Cameras are all about capturing and recording an instant of time by creating some sort of chemical or electric reaction with the photons (light particles) beaming down or bouncing around in any given photographic moment. These instants of captured light are called exposures, and are controlled by three major variables known as the elements of exposure: aperture, length of exposure, and light sensitivity. Aperture refers to the amount of light blocked or allowed in by a mechanical diaphragm inside the camera’s lens. The larger the number on an aperture setting, the smaller fraction of light is allowed to the sensor. Length of exposure is calculated in seconds or fractions of a second; usually this is called shutter speed, and controls how long light sensitive materials are exposed to the light.
