THROUGH THE EYE OF THE CAMERA: LEARNING TO SEE AND SEEING TO LEARN
Purpose: To see the changes in film exposure in relation to Aperture (the Lens) and Shutter Speed (the Camera). Objective: Change the Aperture of the lens without changing the shutter speed on the camera. Background / Context Part 1: The Lens The camera helps us see that shapes, colors, sizes, and meanings change with viewpoint, light quality, distance, and intent. The lens of the camera is what you see through. The lens itself has a circle-shaped opening in a lens (a hole, really) through which light passes to strike the film. This know as the Aperture, which is the variable opening produced by the iris diaphragm through which light passes to the film plane. The Aperture’s iris diaphragm is adjustable, enabling it to be made wider or narrower, thereby letting in more or less light. The Aperture openings are measured in f/stops, which are notched on a ring of the lens (Figure 1). The size of the Aperture is expressed as a number, like “8” or “11”, and is expressed like this: f / 8 or f...
