This lesson is part of the following series:

Fundamentals of Photography - Film & Digital (5 lessons, $40.59)

In this lesson you will learn how to use your camera’s built-in light meter to achieve the desired amount of exposure, how your TTL light meter interprets the scene you are photographing, and how understanding the concept of depth of field will allow you to take fantastic photographs.

It is vital to have the right combination of f-stop and shutter speed in order for the appropriate amount of light to reach your film and achieve a good exposure. To reach the desired result you should use your camera’s built-in light meter. In this lesson you will learn how to use your camera’s light meter and in what conditions it can and cannot be trusted. You will also learn about the different types of metering systems (Manual, Aperture Priority, Shutter Priority, etc.) and how to use them.

TTL light meters do not see the world as we see it; they are in fact “color blind.” This lesson will explain how light meters calculate the exposure by rendering the picture as middle gray and the difference between shooting modes “Aperture Priority” and “Shutter Priority.”

Depth of field is one of the most important tools in photography because it allows you to control the amount of sharpness in your photo and therefore the overall look. In this lesson you will learn what key factors you must understand in order to harness the creative power of depth of field to reach your desired end result.

With the advent of inexpensive cameras, the world of photography was opened up to millions of image makers. This lesson is excerpted from the DVD Learn Photography, Film & Digital, which is an excellent resource for those looking to learn the fundamentals of photography. It is the second lesson cut from the DVD and includes Chapters 4, 5, and 6 (on Exposure Control, TTL Light Meters, and Depth of Field).
