Subject Matter and Definitions
PSA Statement on Subject Matter
There is one hard and fast rule, whose spirit must be observed at all times and applies to all sections offered in PSA recognised exhibitions. The welfare of the subject is more important than the photograph.
This means that practices such as baiting of subjects with a living creature and removal of birds from nests, for the purpose of obtaining a photograph, are highly unethical, and such photographs are not allowed in any PSA exhibitions.
There is also a PSA policy on the use of aerial photography – aircraft, helicopters and drones. This policy can be found at https://psa-photo.org/index.php?psa-policies#drone.
The purpose of this policy is to prevent any interference with other individuals or animals which will or may cause a disturbance in their normal activity or disrupt the way any individuals or animals interact with their environment. Entry in this exhibition requires exhibitors to agree to this and other PSA policies
The content of images must comply with these General Conditions and with the Division and Section definitions listed in these conditions. Images that – in the sole opinion of the judges or the Exhibition Organizers – do not comply are likely to be disqualified so the entrant may be aware of the problem when considering entry into other PSA recognized exhibitions.
PSA Monochrome Definition.
An image is considered to be Monochrome only if it gives the impression of having no color (i.e. contains only shades of grey which can include pure black and pure white) OR it gives the impression of being a greyscale image that has been toned in one color across the entire image. (For example by Sepia, red, gold, etc.) A greyscale or multi-colored image modified or giving the impression of having been modified by partial toning, multi-toning or by the inclusion of spot coloring does not meet the definition of monochrome and shall be classified as a Color Work.
FIAP Monochrome Definition.
A black and white work fitting from the very dark grey (black) to the very clear grey (white) is a monochrome work with the various shades of grey. A black and white work toned entirely in a single colour will remain a monochrome work able to stand in the black and white category; such a work can be reproduced in black and white in the catalogue of a salon under FIAP Patronage. On the other hand a black and white work modified by a partial toning or by the addition of one colour becomes a colour work (polychrome) to stand in the colour category; such a work requires colour reproduction in the catalogue of a salon under FIAP Patronage.
Nature Definition. (Joint PSA and FIAP)
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. Adding a vignette or blurring the background during processing is not allowed.
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.
No modification that changes the truth of a Nature image is allowed. Images may be cropped but no other technique that removes, adds or moves any part of the image is allowed.
Techniques that remove elements added by the camera, such as dust spots, digital noise and lens flare are allowed.
Complete conversion of colour images to greyscale monochrome is allowed. Partial conversion, toning and infrared captures or conversions are not allowed.
Images of the same subject that are combined in-camera or with software by focus stacking or exposure blending are allowed. Multiple images with overlapping fields of view that are taken consecutively and combined in-camera or with software (image stitching) are allowed.
SIE Landscape Definition
This Class encompasses Landscapes, Seascapes, Waterscapes, Skyscapes and/or Cityscapes. Any scenic view where the main subject matter is the view captured and depicted. People may be included in the scene as long as they are ancillary and or supportive of the main subject.
Landscape images entered in this class may be colour or monochrome.
The integrity of the subject must be maintained and the making of physical changes to the landscape is not permitted. You may not, for example, remove fences, move trees or place in the sky from another image. Digital adjustments including dodging and burning, changes to tone & contrast and cropping are allowed, as are High Dynamic Range imaging techniques, stitched panoramas and focus stacking.
Authentic Wildlife
Images entered in Wildlife sections meeting the Nature Photographic Definition above are further defined as one of more extant zoological or botanical organisms free and unrestrained in a natural or adopted habitat.
Landscapes, geologic formations, photographs of zoo or game farm animals, or of any extant zoological or botanical Species species taken under controlled conditions are not eligible in Wildlife sections.
Wildlife is not limited to mammals, birds and insects. Marine subjects and botanical subjects (including fungi and algae) taken in the wild are suitable wildlife subjects, as are carcasses of extant species.
To be eligible for a PSA wildlife medal, the entrant must certify that the photograph complies with both the general nature and authentic wildlife definitions by ticking the “W” box provided.
