Each generation of Nikon flash systems has become more powerful and flexible, but also more complex. Understanding how the latest version, dubbed Creative Lighting System (CLS) works, and how to make the most of it, can be a daunting task, especially since each Nikon flash unit has slightly different controls, and works in a slightly different way. Fortunately, Mike Hagen’s new book, The Nikon Creative Lighting System, provides an easy-to-read, soup-to-nuts, dissection of CLS and specific, detailed instructions on how to use it with just about every model of Nikon flash – both on and off camera.
