To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
What a disappointment! In my opinion, the photography isn't that great, it's a style in which the shots are tightly cropped so you only see a portion, not full frames. So this is not what I was looking for. Had I paged through the book at a book store rather than online I would most likely not have purchased it.
