The word nature is derived from the Latin word natura, or "essential qualities, innate disposition", and in ancient times, literally meant "birth". Natura was a Latin translation of the Greek word physis (φύσις), which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socratic philosophers, and has steadily gained currency ever since. This usage was confirmed during the advent of modern scientific method in the last several centuries.
Within the various uses of the word today, "nature" often refers to geology and wildlife. Nature may refer to the general realm of various types of living plants and animals, and in some cases to the processes associated with inanimate objects – the way that particular types of things exist and change of their own accord, such as the weather and geology of the Earth, and the matter and energy of which all these things are composed. It is often taken to mean the "natural environment" or wilderness–wild animals, rocks, forest, beaches, and in general those things that have not been substantially altered by human intervention, or which persist despite human intervention. For example, manufactured objects and human interaction generally are not considered part of nature, unless qualified as, for example, "human nature" or "the whole of nature". This more traditional concept of natural things which can still be found today implies a distinction between the natural and the artificial, with the artificial being understood as that which has been brought into being by a human consciousness or a human mind. Depending on the particular context, the term "natural" might also be distinguished from the unnatural, the supernatural, or synthetic.
Nature photography refers to a wide range of photography taken outdoors and devoted to displaying natural elements such as landscapes, wildlife, plants, and close-ups of natural scenes and textures. Nature photography tends to put a stronger emphasis on the aesthetic value of the photo than other photography genres, such as photojournalism and documentary photography.
Nature photographs are published in scientific, travel and cultural magazines such as National Geographic Magazine, National Wildlife Magazine and Audubon Magazine or other more specific magazines such as Outdoor Photographer and Nature's Best Photography. Well known nature photographers include Frans Lanting, Galen Rowell, Eliot Porter and Art Wolfe.
Wildlife photography is devoted to capturing animals in their natural habitats. The animals are often photographed in action, such as eating, fighting, or in flight,. Alternatively, more static portraits may be used to show detail of the animal or to depict it in its environment.. Captive or controlled animals are often photographed instead of true wild specimens. It is arguable as to whether this constitutes true wildlife photography.
The macro photography article explains close-up photography in general; however, this is also a type of nature photography. While common macro subjects - bees, dragonflies, and so on - could be described as wildlife, their world also makes for good photography.Color images are not a requirement of nature photography. Ansel Adams is famous for his black and white depictions of nature, while Galen Rowell praised Fujifilm Velvia film for its bright, saturated colors, asking "Who wants to take dull pictures that will last a hundred years?"  Both men distinguish between photography as an expressive art form and sensitometry; an accurate reproduction is not necessary.
