The Leica M system has been with us since 1954. It rapidly became, and has remained the favorite instrument of photographers, especially photojournalists, who, like Henri Cartier-Bresson, seek to ""catch life in the act"", to record ""the decisive moment"". In this Leica M Compendium Jonathan Eastland describes the whole Leica M system from his experience as a professional photographer. He explains how to use, enjoy and get the best out of the cameras and lenses, regardless of age. The latest lenses can be used on the earliest cameras, and vice-versa, and the Visoflex, although no longer made, is now much easier to use with the M6 and its TTL metering. Advice on planning and shooting a story with the Leica and extensive tables of technical data complete this ideal companion for the practical Leica M photographer, as well as for the Leica collector and enthusiast.

From the bestselling author of the acclaimed Chaos and Genius comes a thoughtful and provocative exploration of the big ideas of the modern era: Information, communication, and information theory. Acclaimed science writer James Gleick presents an eye-opening vision of how our relationship to information has transformed the very nature of human consciousness. A fascinating intellectual journey through the history of communication and information, from the language of Africa’s talking drums to the invention of written alphabets; from the electronic transmission of code to the origins of information theory, into the new information age and the current deluge of news, tweets, images, and blogs. Along the way, Gleick profiles key innovators, including Charles Babbage, Ada Lovelace, Samuel Morse, and Claude Shannon, and reveals how our understanding of information is transforming not only how we look at the world, but how we live.
