I'm delighted by the book, which forms a beautiful complement to the manual Canon, intelligently written and very practical for photo enthusiasts. Read this reading brought me what I expected, ie open the horizon using the 500D provide clues to go further, while providing clarification and guidance on the use of appliance in specialized areas. Me who loves the macro, which works mainly in raw, which always seeks the best possible results while being an amateur, I found in the work of the author all I was looking for. Highly recommended for photo enthusiasts who consider, like me, the digital camera is a tool of expression which needs to be mastered. The title of the book is also very well chosen. An excellent price / quality ratio.
