Nature means Images where living organisms are the primary subject matter.The story telling value of an Image will normally be weighed more than the pictorial quality.

Nature includes:
  * Images taken with subjects in controlled conditions such as zoos, game parks, botanic gardens, aquariums and enclosures where the subjects are dependent on man for food. Scientific bands, tags or collars are permissible.

Nature excludes:
  * Images where the subjects are obviously domestic animals or plants.
  * Images where an obviously artistic treatment has been applied. Processing of the captured image, by cropping, exposure adjustment, colour correction, noise minimisation, dodging/burning, HDR, focus stacking and sharpening, is permitted, as is cloning of image defects and minor distractions including overlapping elements.

An Image appearing to meet these criteria will be acceptedas Nature.

The Judges will normally assume that any Image presented to them is eligible. Access to some biological subjects may be restricted. Where that is relevant, then Photographers warrant that they have followed relevant codes of practices and hold any necessary licences.

See also the Royal Photographic Society's Nature Photographers' Code of Practice, which is neatly summarised as "There is one hard and fast rule, whose spirit must be observed at all times. The welfare of the subject is more important than the photograph."
