The book is very well conceived and appears to address all aspects of lightroom5, and does not reject a beginner. The screenshots are small but the photos make it easy to see them implemented alterations, however tiny texts are not legible, but the explanations in the margins are clear and complete. one of the advantages of this book over competitors is to offer a provided index, but .... the one I received, though the ISBN and bar code are identical to the model that can be flick is totally wrong and makes it unusable. No pages are found, it seems that the book that I have received has made the printing error object on his forefinger.
