DIGITAL ENTRY REQUIREMENTS
An entry consists of three elements:
JUDGING METHOD
Judging is to take place Onsite.
Electronic images will be displayed on an LG 65” passive UHD OLED 3D-TV with 3840 horizontal x 2160 vertical native resolution (model OLED65C6P).
Award session will be held with all of the judges together Onsite.
Distribution of images shall be in the same round order as submitted by the entrant, but they shall not appear to the judges consecutively.
At no stage will exhibition software allow a judge to view all the entrant’s images together. Target Acceptance Range: 39 – 45%
EXHIBITION REQUIREMENTS (Part B)
Applicable Rules: This exhibition will be conducted in accordance with the rules of the PSA.
Entry Requirements: This exhibition is open to everyone; however, an entry may be rejected when the exhibition chair believes the entry does not conform to PSA exhibition rules and these Conditions of Entry. Membership in any photographic organization is not required. Neither awards nor acceptances will be granted to any entrant who is on the PSA Penalties List for Ethics Violation, and entry fees are not refundable in these circumstances. Throughout this document, entrant, author and photographer are used interchangeably, and each term refers to the person who is the original creator of a submitted image. Entrants are required to submit their own entries with properly sized images.
PSA Star Ratings: To receive star ratings credit from PSA, entrants must provide their names and country exactly the same way in each exhibition. Aliases are not permitted. Please contact PSA in the event of a name change or relocation to another country. Using one’s name differently in different exhibitions exposes the entrant to the risk that many of their acceptances may not be recognized in PSA Star records.
Reproduction: Entrants grant sponsors free reproduction rights for exhibition-related media, including low-resolution web posting. Entries will not be accepted from entrants who restrict reproduction rights. PSA may request specific permission for educational use under mutually agreed terms. If an image violates PSA’s exhibition rules or its Ethics Policy, PSA may reproduce the image without permission for educational purposes or to illustrate rule violations, with the entrant's name withheld. Neither PSA nor the exhibition assumes liability for copyright misuse.
Re-use of accepted images: Any image that has been accepted in this exhibition, past or present, may not be entered again in the same division star ratings class in any future instances of this exhibition. It may be entered in any other PSA recognized exhibitions but must always have the same title. Re-titling in another language is not allowed.
Entry: An entry consists of up to 4 images per section, with each image limited to 20 total acceptances per star path. Identical or similar images are prohibited within the same exhibition, and if similar images are uploaded, all will be disqualified across all sections. While similar images may be entered in different exhibitions, they may later be disallowed during star/diamond/galaxy application reviews. Similar images are those which are practically equivalent, as defined on the page available at https://psa-services.org/ES/#entrants. To avoid disappointment, do not enter images that are practically equivalent. Watermarks, copyright text or any other visible markings are prohibited.

Protection of Entrants' Personal information: By entering this exhibition, you agree to comply with PSA rules and policies, and consent to the exhibition chair and recognized organizations holding and processing your personal details for exhibition purposes, and accept that your participation status (name, country, sections/photos entered) and results will be made public in status lists, galleries, and catalogs.

SUBJECT MATTER AND SECTION DEFINITIONS:
While the following section provides summaries of PSA definitions, entrants must refer to the PSA website for the authoritative definitions for each Division: https://psaphotoworldwide.org/page/exhibitions
Image Creation and Authorship
Summary: All submitted images must be entirely the photographer's original work, including post-processing, with every pictorial element captured by the submitting photographer. Images must not incorporate or present other artists’ work as the photographer's own, in whole or in part (clip art, stock images, replacement skies, photos of others’ artwork, AI-generated content, etc).
The term author refers to the person who is the original creator of a submitted image; photographers may own the rights to use purchased content; however, authorship requires that all visual elements in the submitted photograph be personally created by the photographer. Photographers must retain copyright ownership of all visual elements contained within any submitted image, including composites. A violation of this rule constitutes plagiarism, a serious PSA ethics offense.
Artificial Intelligence
Summary: Recognizing the rapid evolution of AI software, this rule is subject to change. For the latest rules, consult the AI Statement on PSA’s website. AI photo editing tools which enhance, adjust, or intelligently modify what was already captured in your photograph are permitted, provided they use only visual information already present in your photograph. Outpainting tools (generative fill) which allow you to expand a cropped image using a context-aware extension of the original photo are permitted, unless restricted by the Division’s definition. Other generative AI tools that generate new synthetic visual content based on external image data not originally present in the author’s photograph are prohibited, regardless of how small the edited area. Any person who violates this AI rule shall be banned from PSA exhibitions for a period ranging from 3 years to permanent exclusion. See additional AI notes in the editing matrix below.
Subject Matter
Summary: PSA's fundamental rule prioritizes animal welfare over photography, prohibiting baiting with live creatures, nest disturbance, endangering subjects, or depicting feeding of live prey to captive animals. Aerial photography must not disturb individuals or animals and must comply with local regulations. The images must comply with the division and section definitions listed on the PSA website; images that do not comply will be disqualified by the judges. Participation in PSA exhibitions is conditional on entrants accepting these policies.
Color versus Monochrome (Black and White)
Within photography an image is either monochrome or color; there is no third option.
Open Definition (3DD) Color or Monochrome
Images of any subject, employing any allowed technique.
Altered Reality Definition (3DD) Color or Monochrome
Altered reality 3DD images consist of one or more stereoscopic photographs which have been manipulated by combining multiple images into a single image, and/or by changing the color, form, shape, etc. of a single image, or a combination of these two techniques.
Landscapes / Seascapes / Cityscapes Definition (3DD) Color or Monochrome
Landscapes / Seascapes / Cityscapes 3DD images portray the natural world in all its vastness and beauty, from serene vistas to dramatic terrains. This theme focuses on capturing the essence of outdoor environments, showcasing the interplay of light, texture, and atmosphere. Urban, rural or city scapes, landscapes, water scapes or sea scapes are all encouraged. People may be present in the scape, but should not dominate the scene.
Exhibition Specific Conditions
Judging of all three sections will be conducted by all three judges in the same room.
