70% of this book has nothing to do with the D200 but is basic photography concepts instead. The small percentage that actually was about the D200 you can get from the owners manual. Nothing of use here unless you want a repeat of the owners manual and a bunch of basic photo tips.
The vast majority of the content in this book dealts directly with the D200, providing specific tips that will help you set up the camera and learn to use its features. In my copy, the first six chapters, Quick Tour, and the Troubleshooting appendix all concentrate on the D200, in much more detail than the Nikon manual, and much more clearly, too! Even the menu illustrations, which are in full color, are more informative than those in the tiny manual. Chapter 7 is the only general photography chapter. It provides guidelines for shooting photos in 20 common picture-taking situations. Although some of the information is basic to intermediate photography in this chapter, the included tips are all specific to the D200. There is no comparison between this full-color book and the owners' manual at all.
The guidelines are nothing specific to the D200. It is the same old photo basics for people without training. I suppose it would be okay to write such a book on the F6 too to include basic photo work even though it is a professional's camera. This book is worthless. It isn't specific to the D200 at all as mentioned.
In a nutshell:
Take the Nikon owners manual, change around some words. Then make some other chapters on basic photography. Publish and then try and sell.
If having color pictures and larger text is appealing then maybe it works for you (what a stretch to try and make this book sound good, lol). My advice - visit the eye doctor - the print isn't any smaller than other owner manuals, and nevermind "color" since it doesn't matter when looking at technical information (and the camera features are on a black body with white print,,,,lol,,,color?).
