Nature photography records all branches of natural history except anthropology and archaeology. This includes all aspects of the physical world, both animate and inanimate, that have not been made or modified by humans.
• Nature images must convey the truth of the scene that was photographed. A well-informed person should be able to identify the subject of the image and be satisfied that it has been presented honestly and that no unethical practices have been used to control the subject or capture the image. Images that directly or indirectly show any human activity that threatens the life or welfare of a living organism are not allowed.
• The most important part of a Nature image is the nature story it tells. High technical standards are expected and the image must look natural.
• Objects created by humans, and evidence of human activity, are allowed in Nature images only when they are a necessary part of the Nature story. Photographs of human-created hybrid plants, cultivated plants, feral animals, domesticated animals, human-created hybrid animals and mounted or preserved zoological specimens are not allowed.
• Images taken with subjects under controlled conditions, such as zoos, are allowed.
• Controlling live subjects by chilling, anaesthetic or any other method of restricting natural movement for the purpose of a photograph is not allowed.
EDITING GUIDELINES - Processing or editing must be limited to making the image look as close to the original scene as possible, except that conversion to grayscale monochrome is allowed. Removing, adding to, moving or changing any part of an image is NOT allowed, except for cropping and straightening. (APS definition)
