Apress, 2010. — 301 p. — ISBN: 1430228415, 978-1430228417.Digital image post-processing and open-source software are exciting topics; this book is the fusion of both. How cool is that? After you read this book, you will be able to edit your images for free.
This book starts with some background information about photography and digital images to give the reader a common base. Then, several image post-processing techniques are presented with ascending difficulty, from simple resizing or cropping to more advanced subjects such as high dynamic range (HDR) imaging, distortion correction, or panoramas. Armed with these techniques, using the best open-source tools available, you will be ready to start editing your images for free. In each case, I will show you the best free tools for the job. Finally, as an added bonus, the last two chapters cover extra stuff: video processing for creating your own movies from single video clips and CHDK to enhance your camera features.
The first chapter of the book introduces general photography concepts. You will learn common concepts used in photography so that you can control your camera to take the shots that you want. Understanding these concepts is the key to shooting a good photo, which in turn is the starting point for image editing.
The second chapter describes all the details of digital images. Because you are going to work with digital images, in-depth knowledge is beneficial before you start editing.
The third chapter covers the simplest and most common post-processing techniques. Every photographer often needs to resize or crop their images so that they fit in the specific medium they want to present. All these operations and more are presented in this chapter.
The fourth chapter explains how to control color in your images. Everything that you need to know is here. The fifth chapter covers the most commonly used filters in digital photography, such as noise reduction, blur, or the unsharp mask. The sixth chapter covers the photo retouching techniques that photographers use to fix images with small problems such as skin blemishes, removing small objects, and so forth.
Chapter 7 covers a more advanced technique, HDR. You will learn how to create those images from ordinary pictures. Chapter 8 covers distortion correction. It shows you how to correct the distortion produced by perspective and lenses. In Chapter 9, you will understand how to take the images needed for making panoramas as well as how to create them.
The last two chapters cover bonus material. Chapter 10 teaches you how to create movies from your video clips, and Chapter 11 describes how to use CHDK to enhance your camera’s features.
