There are four sections, all DIGITAL:
Open Color // Open Monochrome // Nature // Travel
Each photo can be presented in only one section. When an entrant submits images which are significantly similar to each other, only one of the images will be accepted, even if the images are entered in different sections.
Entries must originate as photographs made by the entrant. All techniques are permitted.
FIAP definition of Nature Photography: Nature photography depicts living, untamed animals and uncultivated plants in a natural habitat, geology and the wide diversity of natural phenomena, from insects to icebergs. Photographs of animals which are domesticated, caged or under any form of restraint, as well as photographs of cultivated plants are ineligible. Minimal evidence of humans is acceptable for nature subjects, such as barn owl or storks, adapting to an environment modified by humans, or natural forces, like hurricanes or tidal waves, reclaiming it. The original image must have been taken by the photographer, whatever photographic medium is used. Any manipulation or modification to the original image is limited to minor retouching of blemishes and must not alter the content of the original scene. After satisfying the above requirements, every effort should be made to use the highest level of artistic skill in all nature photographs.
PSA definition of Nature Photography: Nature photography is restricted to the use of the photographic process to depict observations from all branches on natural history, except anthropology and archeology, in such a fashion that an informed person will be able to identify the subject material and to certify as to its honest presentation. The story telling value of a photograph must be weighed more than the pictorial quality. Human elements shall not be present, except on the rare occasion where those human elements enhance the nature story. The presence of scientific bands on wild animals is acceptable. Photographs of artistically produced plants or animals, mounted specimens, or obviously set arrangements, are ineligible, as is any form of manipulation that alters the truth of the photographic statement. No elements may be moved, cloned, added, deleted, rearranged or combined. No manipulation or modification is permitted except resizing, sharpening, cropping, selective lightening or darkening, and restoration of original color of the scene. No special effect filters can be applied. Any adjustments must appear natural.
A Photo Travel image must express the feeling of a time and place, portray a land, its people, or a culture in its natural state, and has no geographical limitations. Ultra close-ups which lose their identity and studio-type model shots are unacceptable. Techniques that add to, relocate, replace or remove any element of the original image, except by cropping, are not permitted. Techniques that enhance the presentation of the image, without changing the photo travel content, are permitted. All adjustments must appear natural. The removal, or manipulation, of colors contained within the original image to enable the production of monochrome images is permitted.
PSA definition of Monochrome Photography: A monochrome image is defined as having varying shades of no more than one color (various shades of that color from very light to very dark) but it may be any single color. Multi-toned images (various shades of two or more colors) and grayscale images withan added accent color are not acceptable in Monochrome Class sections and must be entered in Color Class sections.
