Wildlife photography is a genre of photography concerned with documenting various forms of wildlife in their natural habitat. It is one of the more challenging forms of photography. As well as requiring sound technical skills, such as being able to expose correctly, wildlife photographers generally need good field craft skills. For example, some animals are difficult to approach and thus a knowledge of the animal’s behavior is needed in order to be able to predict its actions. Photographing some species may require stalking skills or the use of a hide/blind for concealment.
