National Grographic - the world famous photography magazine. Or at least it started out all about photography but now it has evolved to become the world's authority on natural science, archaeology, conservation, arts, culture and even environmental issues. All these mainly through their photos. Or if you are like me, just visit this site for all their beautiful and sometimes even awe-inspiring photographs. The magazine National Geographic is their official journal showcasing photography throughout the world. It comes in 12 issues per year. Subscribe to it, not really that expensive considering the quality of the articles and the photos.
