The 'From Snapshots to Great Shots' series is a growing one and covers a variety of topics mostly on one aspect of photography, such as landscapes or black and white, or in a couple of instances to date on a specific camera. This is one of those and the camera, although priced for and with a feature set aimed at the user for whom this may well be their first serious camera or dSLR. However, there is one feature of this model that rather sets it aside - and rather far to the side - of many of its similarly priced and featured alternatives; that is its 24 megapixel capability!
The purpose of this book is not to replace the camera manual, although it could, but to expand upon it. In most instances, the manual may explain what a certain button or dial will do and under what circumstances and may also include a list of those items and adjustments that exist within its several layers of menu but does not have the space to explain some of them more fully. Some are quite obvious and speak for themselves but when or why you should allow ISO settings to be controlled by the camera or selected manually may not be fully explained. There are many others where this may also be true, not least the various image qualities on offer. The book offers an opportunity to explore the camera a little further, to add sections which the manual omits and possibly, should you choose, to store it in the gadget bag or otherwise with the camera should you need to clarify something at some later date.
This is one of the first books from any publisher to appear for this model. Whether or not it is any better or worse than its competitors will depend solely whether or not it answers the questions you may have. That isn't a question I can answer for you. You will need to decide.
Of those titles I have seen, the series is one that is worthy of consideration by any new(ish) photographer or one wishing to further explore the subject. Those of its titles that comprise 'camera guides' are slightly different and are likely to be purchased either by those who had recently made the purchase or are seriously considering doing so. There are reviews to be found on-line, but this provides a far more detailed - but different - look at the camera.
