Concepts of photography are the underlying principles that apply regardless of the camera you are using. They include such things as how sharpness and exposure affect your images and the way they are perceived by viewers. Understanding concepts answers the "why" kinds of questions you might have about photography.
Procedures are those things specific to one kind of camera, and explain step-by-step how you set your camera's controls to capture an image just the way you want to. Understanding procedures gives you the answers to the "how" kinds of questions you might have. For example, among the many things you'll see are how to throw the background out of focus, how to keep everything in a landscape sharp, how to avoid or creatively use blur; how to photograph sunrises, sunsets; and how to take pictures at night with city lights, the moon, or fireworks.
This book is organized around the concepts of digital photography because that's how photographers think. You think about scenes and subjects, highlights and shadows, softness and sharpness, color and tone. The procedures you use with the Canon PowerShot S100 camera are integrated throughout the concepts. They appear in those places where they apply and are described step-by-step. This integrated approach lets you first understand the concepts of photography and then see step by step how to use the PowerShot S100 in all kinds of photographic situations.
