A glittered face creates the illusion of the night sky. A dancer’s pose mimics a tree. Mother and child powerfully stare through their black and white portrait. These and other images can be found inside James Houston's masterful new photography book, Natural Beauty($50, Damiani). The subjects? Emma Watson, Adrian Grenier, and cover girl Christy Turlington, among many others. With 120 striking photos, the book evokes the relationship between the natural world and the human form and aims to raise awareness for environmental conservation and sustainable lifestyles. Hence the book’s World Earth Week release and Houston’s pledge to donate proceeds to Global Green USA. Natural Beauty is currently available for presale on Amazon, and will hit select bookstores, on April 30.
