A nature photograph depicts observations from all branches of natural history, except anthropology and archaeology. Nature may include botany, zoology, or geology when depicted in such a fashion that a well-informed person will be able to identify the subject and to recognize its honest presentation. Human elements shall not be present unless they enhance the nature story and are unobtrusive. Photographs of mounted specimens, set arrangements, derivations, or any form of photographic manipulation that alters the truth are ineligible, with the exception of detailed micro or macro photographs. Scientific banding is permitted on wild animals. Photos of captive animals are allowed. If the subject is non-captive wildlife, the entrant may indicate this in the title to the image.
