Who is This Book For?
It is aimed primarily at DSLR users, but whether you shoot with a Nikon, Canon, Pentax, Sony or Olympus, the information in this book can pretty much be applied to every camera. The hints and tips included in Volume 3 are not necessarily aimed at more advanced photographers, just at photographers who have already read and applied some of the knowledge gleaned from volumes 1 and 2.
Do you need to have read volumes 1 and 2 before reading volume 3? It depends. If you are new to Digital SLRs, and have a limited photographic background, it may be best to work your way through volumes 1 and 2 first. There are lots of things that you will learn and can apply to your photography in this book, but in volume 3, Kelby builds upon what he teaches you in volumes 1 and 2, and then takes it to the next level.
Consequently, there is a certain amount of assumed knowledge taken for granted, but not a huge amount. If, however, you are a more experienced photographer, or are looking for a great gift for a photographer that has read and enjoyed either or both of the previous volumes, then volume 3 of would be a great purchase.
