4. THINGS TO CHANGE: more cameras so each students have time to "learn" about the camera settings.

Chapter 02: Lens

Forming an image. Although a good lens is essential for making crisp, sharp photographs, you don’t actually need one to take pictures. A primitive camera can be constructed from little more than a shoe box with a tiny pinhole at one end and a digital sensor, a piece of film, or a sheet of light-sensitive photographic paper at the other. A pinhole won’t make as clear a picture as a glass lens, but it does form an image of objects in front of it.

A simple lens, such as a magnifying glass, will form an image that is brighter and sharper than an image formed by a pinhole. But a simple lens has many optical defects (called aberrations) that prevent it from forming an image that is sharp and accurate. A modern compound lens subdues these aberrations by combining several simple lens elements made of different kinds of glass and ground to different thicknesses and curvatures so that they cancel out each other’s aberrations.

The main function of a lens is to project a sharp, undistorted image onto the light-sensitive surface. Lenses vary in design, and different types perform some jobs better than others. Two major differences in lens characteristics are focal length and speed.

Lens focal length is, for a photographer, the most important characteristic of a lens. One of the primary advantages of a single-lens reflex camera or a view camera is the interchangeability of its lenses; photographers own more than one lens so they can change lens focal length. More about focal length appears on the following pages.

Lens speed is not the same as shutter speed. More correctly called maximum aperture, it is the widest aperture to which the lens diaphragm can be opened. A lens that is “faster” than another opens to a wider aperture and admits more light; it can be used in dimmer light or with a faster shutter speed.

Chapter 03: Light and Exposure

Your digital camera’s sensor is light sensitive. Like film, when a sensor is exposed to light, a change occurs that can be recorded. Light is the visible part of the electromagnetic energy that exists in a continuum from radio waves through visible light to cosmic rays. These energy forms differ only in their wavelength, the distance from the crest of one wave to the crest of the next. The visible part of this spectrum, the light that we see, ranges between 400 and 700 nanometers (billionths of a meter) in wavelength.

Exposing your pictures correctly (that is, setting the shutter speed and aperture so they let in the correct amount of light for a given ISO and scene) makes a big difference if you want a rich image with realistic tones, dark but detailed shadows, and bright, delicate highlights, instead of a too dark, murky picture or a picture that is barely visible because it is too light.

At the simplest level, you can let your automatic camera set the shutter speed and aperture for you. If your camera has manual settings, you can calculate them by using a hand-held or built-in exposure meter to make an overall reading of the scene. You can even use a simple chart of general exposure recommendations like the one on page 7. In many cases, these standardized procedures will give you a satisfactory exposure. But standard procedures don’t work in all situations. If the light source is behind the subject, for example, an overall reading will silhouette the subject against the brighter background. This may not be what you want.

You will have more control over your pictures—and be happier with the results—if you know how to interpret the information your camera or meter provides and can adjust the recommended exposure to get any variation you choose. You will then be able to select what you want to do in a specific situation rather than exposing at random and hoping for the best.
