Nature photography is split in to 2 sub classes, nature and wildlife.
Nature photography is the use of images to depict natural history, except anthropology and archaeology in such a way that a person will be able to identify the subject material and certify its honest presentation Human elements shall not be present, except where those human elements are integral parts of the nature story such as nature subjects, like barn owls or storks or where those human elements are in situations depicting natural forces, like hurricanes or tidal waves. Photographs of human created hybrid plants, cultivated plants, feral animals, domestic animals, or mounted specimens are ineligible, as are any form(s) of manipulation that alters the truth of the photographic statement.
No techniques that add, relocate, replace, or remove pictorial elements except by cropping are permitted. You are allowed to enhance the image with techniques such as HDR, Focus Stacking, Dodge & burn etc. Techniques that remove elements added by the camera, such as dust spots, digital noise, and film scratches, are allowed as well
Stitched images are not permitted, Infrared images are not allowed. In summary Nature can be anything in the natural world. Including organisms in controlled conditions. eg. Zoos farms and botanical gardens.
Wildlife photography. All the rules for nature apply here with the only exception that organisms must be free and unrestricted.
We as a club normally treat these classes as one subject unless otherwise stated.
