Natural Light Control is part of our special week-long event Lighting Toolkit.
Join award-winning photographer Tony Corbell for an in-depth exploration of how light works and how it can be controlled to create dramatic images.

The Grand Canyon will forever remain unexplored and untouched. No one will ever be able to visit it. The area is inhospitable, the journey there too dangerous. This is the conclusion of a failed expedition, drawn by Joseph C. Ives in 1858. But he was wrong. Since then, more than 100 million tourists have visited the Grand Canyon of the Colorado River.The Grand Canyon is a unique area, painstakingly carved into stone by one single river over a period of millions of years. Inch by inch. The result is a canyon of indescribable and unique beauty. A canyon that overcomes some 4000 metres from the summit of its highest elevation, to the banks of the Colorado, thereby embracing five climate zones.This is also why the Grand Canyon can boast an unrivalled density of flora and fauna. Desert and mountain dwellers live here in the immediate vicinity, sharing a unique biosphere.Nowhere else can the geological era be so perfectly determined by means of the rock formations adjacent to the ancient paths, that lead from the edge of the canyon to the riverbanks of the Colorado.2 billion years of Earth’s history made comprehensible. For this reason alone, the Grand Canyon is rightfully a World Natural Heritage Site worthy of protection and an ideal symbiosis of economy and ecology.

The Yellowstone National Park is the oldest national park in the world. It is home to a landscape with the world’s highest concentration of geysers and thermal springs, as well as being famous for its herds of bison that roam the plateaus of the highlands.The herds are often accompanied by wolves, which were reintroduced to the Yellowstone National Park around ten years ago. Black bears, beavers and wapitis also inhabit the park, which the locals affectionately refer to as “The Yellowstone”.A park justifiably recognised by UNESCO as a World Natural Heritage Site. After all, in addition to its impressive flora and fauna, the national park provides us with an insight into the history of the Earth’s origins. It transports visitors back into a time when volcanoes and the forces of Mother Nature once shaped our world. These forces can be experienced when huge fountains of water shoot high into the sky and pure energy from the Earth’s interior finds an outlet.The World Natural Heritage Yellowstone National Park – a film in which nature plays the leading role, thereby illustrating why it makes sense to both preserve and protect it.

As the founder of Resources for Infant Educarers (RIE), Magda Gerber has spent decades helping new mothers and fathers give their children the best possible start in life. Her successful parenting approach harnesses the power of this basic fact: Your baby is unique and will grow in confidence if allowed to develop at his or her own pace. The key to successful parenting is learning to observe your child and to trust him or her to be an initiator, an explorer, a self-learner with an individual style of problem solving and mastery.

One of the earliest New World naturalists, Jose Celestino Mutis began his professional life as a physician in Spain and ended it as a scientist and natural philosopher in modern-day Colombia. Drawing on new translations of Mutis's nearly forgotten writings, this fascinating story of scientific adventure in eighteenth-century South America retrieves Mutis's contributions from obscurity.

The Handbook of Natural Language Processing, Second Edition presents practical tools and techniques for implementing natural language processing in computer systems. Along with removing outdated material, this edition updates every chapter and expands the content to include emerging areas, such as sentiment analysis.

This study draws on data from numerous sources that support the paradigm of natural hybridization as an important evolutionary process. The review of these data results in a challenge to the framework used by many evolutionary biologists, which sees the process of natural hybridization as maladaptive because it represents a violation of divergent evolution.
In contrast, this book presents evidence of a significant role for natural hybridization in furthering adaptive evolution and evolutionary diversification in both plants and animals.

Evolutionary biologist and paleontologist Stephen Jay Gould has perfected the art of the essay in this brilliant new collection. These thirty-four essays, most originally published in Natural History magazine, exemplify the keen insight with which Dr. Gould observes the natural world and convey the infectious enthusiasm for fossils and evolutionary theory that has made his books award-winning, national best-sellers.

Edited by two leading experts on the languages of West Africa, this volume is the very first book to handle a range of topics in the syntax of Kwa, a branch of the Niger-Congo language family spoken by approximately 20 million people in Côte d’Ivoire, Ghana, Togo, and Benin and in the extreme southwestern corner of Nigeria.
