Most image editors include several powerful tools to improve your pictures. Among them, the histogram is used as a basic analysis tool, then Levels and Curves tools are used to perform the required adjustments.
Levels adjustment allows for an initial light and contrast correction. Curves adjustment adds the flexibility to control every single tone or shade separately.
From a basic description of these tools, this book introduces different terms and concepts gradually, with increasing complexity, to show a wide range of edition possibilities.
From simple changes such as contrast or illumination correction, the book goes up to traditional colouring, film simulation and basic printer callibration techniques for home devices.
