SEBASTOPOL, Calif. -- The Nikon D90 camera has exploded on the digital photography market, with a myriad of new features, including the industry-first HD video capability. Even better, the camera comes with a manual that details each and every button in reasonably clear language.

But as author Ben Long says, "Knowing what each button on your camera does won't necessarily mean you can shoot great pictures." That's the idea behind his newest book in O'Reilly Media's Companion series: The Nikon D90 Companion ($24.99).

While the automatic systems in the Nikon D90 mean you can shoot snapshots that are almost always properly exposed and possessed of great color, if you want to go further and create images that express something more than a simple documentation of an event, then you need to know something of the art of photography.

This book is intended to serve as a full-on photography class, one that covers everything including technical matters and exposure theory, composition theory, and how to find images and expand your visual sense. However, unlike a regular photography class, this book is built specifically around the D90, which means every concept is written about in terms of the D90's controls and features.

With Long's creative tips and technical advice, you have the perfect field reference to help you capture stunning pictures anywhere, anytime. The Nikon D90 Companion will show you how to:

• Take creative control and go beyond automatic settings

• Capture decisive moments, including fast-moving objects

• Discover ways to use a flash indoors and outdoors

• Learn about different lenses and when to use them

• Understand the options for shooting RAW and whether it's right for you

• Shoot high-definition video with the D90

By the time you're done with this book, you'll not only know how all the D90's controls function, but you'll also know how to recognize a good photo and how to use the D90's controls to represent that subject as a compelling image. In other words, you'll be a better photographer, whether you're shooting simple snapshots or aiming for something more.
