Before entering, please read the Rules and Guidelines and Digital Specifications & Adjustment Guidelines carefully as all entrants have to acknowledge acceptance of them during the online registration process.

Rules and Guidlines

  • Each entrant may enter up to 10 still photographs or films.
  • All photographs and films entered must have been completed since 1 January 2015. 
  • Entries must be submitted as digital files only. For initial entry, all still photography images must be submitted as JPEGs, saved at a high quality level, e.g. 10 in Adobe Photoshop, with a maximum file size of 0.5MB. SEE DIGITAL SPECIFICATIONS SECTION BELOW FOR FURTHER DETAILS.

  • Do not add a signature to any entry as judging is done anonymously and entries with overlay signatures will not be accepted.
  • It is the entrant’s responsibility to ensure that all the necessary permissions are obtained from people featured in the entry.
  • All entries, both still photography and film, should be a faithful representation of the original scene and localised adjustments should be used appropriately. Some digital adjustment or editing is allowed, but entrants should understand that the objective is to remain faithful to the original experience, and to never deceive the viewer or misrepresent reality.

Digital Specifications

The following guidelines explain the required specifications for each category at the different stages of the competition and exhibition. Please ensure that your entries adhere to these guidelines. If any further queries, please check the HELP & FAQs section or contact the exhibition organisers by email.


  • Still Photographs – initial entry: all still photographs must be submitted as JPEGs, saved at a high quality level, e.g. 10 in Adobe Photoshop, with a maximum file size of 0.5MB. Each image file must be named with your surname, first name and brief title e.g. SmithJohn_Title.jpeg. Whilst work titles may be too long to be used as image names, a section of your title would be adequate.
  • Films – initial entry: entrants are required to provide an HTML link in order to view the full film via YouTube, Vimeo or similar. Each clip should be a minimum of 5 seconds and a maximum of 5 minutes long, and can include an audio track. The HTML link must be labelled in such a way that it is easily identifiable as your work, i.e. include your name in the file link. If your Vimeo account is password protected please paste the password into the ‘Vimeo Password (if applicable)’ field for that entry on the entry form. Please do not paste it in with the link, as this will corrupt the link.
  • Still Photographs -proof of authenticity: original digital camera RAW files will be required if your image is shortlisted. Digital images captured as JPEG are allowed, providing the original un-retouched JPEG is available for inspection. Any work created from more than one original (e.g. stitched images), must be declared as such, and the original captured images should be available for inspection when requested.
  • Films – exhibition: high-resolution files will be needed if selected for exhibition. Entrants will be required to either upload these file to the competition FTP site, or to send a DVD to the exhibition organisers. These details will be confirmed if selected for exhibition.
  • Still images – exhibition: for printing in all media and for inclusion in the exhibition, a high-resolution image (preferably TIFF) will be requested if your image is selected for exhibition. This should be 8-bit, Adobe RGB (1998) at 300ppi. Images within the Exhibition will be printed to an approximate maximum of 920mm along the longest dimension.
