Through the Lens is an excellent collection of National Geographic photos, and for only $30, well worth the cost. The book has several well known photos, as well as other beautiful, but not as publicized, pictures. The book is divided into sections based on continents, which (usually) makes it easier to find a specific picture. This book does have its share of problems however. There's no index, so you can't look for pictures with a specific theme. The majority of the pictures are centered in the middle of the two pages, so the middle of the pictures disappear into the binding. The pages are another problem entirely. The book is printed on glossy paper that absorbs liquid (apparently). Oil from your fingers is left as prints or smudges, even if you only are touching the page for a few seconds. These marks DO NOT disappear over time, and you can espeacially see them on the black pages. Even with these problems, this book is worth getting for the spectacular pictures inside.
