I wrote a book about editing photos using free software. The title for this book is “Beginning Digital Image Processing: Using Free Tools for Photographers”.
I have been using great open source software for editing all my images over the years. Many times I talked to other people about these programs but only a few knew about them and what they are capable of. After one of those conversations, I decided to write a book about these free tools so that they are known and used by more people.
The first two chapters are used to give the reader a solid introduction in photography and digital images. That way, everybody starts at the same level. The next chapter covers the most basic photo editing techniques, such as resizing or cropping. In chapter four, the concept of color in general is covered, for example white balance, brightness and contrast, hue and saturation, etc. In chapter five I describe some of the most important filters, such as noise removal, blur and the unsharp mask. Chapter six deals with photo retouching, such as red-eye removal, object removal, a.k.a. content aware fill, selective colorization, and more. Chapter seven talks about High Dynamic Range images (HDR) and how to create them. Chapter eight is about distortion correction, caused by the lens as well as the perspective. In chapter nine I teach you how to stitch normal images together to create a panorama. Chapter ten deals with movie editing and chapter eleven covers Canon’s Hack Development Kit (CHDK) which enhances some Canon point and shoot cameras. In the appendix are the instructions on how to install all the software that I use for Microsoft Windows and Ubuntu. In this book, I show you how to use Gimp and some of its plug-ins, Hugin, Imagemagick, Luminance HDR (formerly known as Qtpfsgui), UFRaw, Avidemux and ExifTool.
