As the other reviewers have said, there is so much information in this book and it does cover every aspect and provides clear instructions. It will do the job if you want to know about elements 5. But there are a number of irritating faults:
1) The author's humour is silly and childish. This is ok in small doses but when, in many areas, nearly every other line has this silliness, it becomes wearing. Also, when you want to understand how to do something and the meaningful text is perhaps 4 lines, it is annoying to have to read through more than ten lines of silliness to get to the useful text. eg "...an entire chapter devoted to Raw. So why a whole chapter? ........ (2) I needed the extra pages to get my page count up; (3) I really didn't need the page count, but you can't be sure of that...." Drivel and unnecessary.
2) There are too many photographs that claim to show a problem that needs putting right but which are not magnified enough to show the problem. The net result is that for things like sharpness and chromatic abboration, it is impossible to see the difference. The main concern is that, whereas I think I know what I am looking for, the beginner might not and so is left wondering what it is that they are curing.
3) Finally, there are a couple of screenshots that show a different detail in the screen from mine. If this is because the US version is different from the UK version, fine, but they should say "US Version". Otherwise, can I trust that this is truly elements 5 or just a rehash of elements 4 with poor editing? For example, for editing RAW, one page refers to a "Shadows" slider beneath "Exposure" whereas the elements I have has three sliders: "Recovery", "Fill light", "Blacks".
This book will certainly cover everything you need, but then I would expect every book to do that. Despite its failings, it will work for you, but just be prepared for the imperfections.
