Entries must be submitted as JPEGs, saved at a high-quality setting of at least 8 in Photoshop, Adobe RGB (1998), and at 1920 pixels along the longest dimension. Please do not include borders, watermarks or signatures.
Once your files have been uploaded and saved through the entrant's portal, they are automatically included in the competition. You will be able to log in to add or delete images up until the competition closes.
If your image is selected for the Final Round of judging you will need to provide a RAW file, original untouched JPEG (with a range of ‘before’ and ‘after’ original untouched JPEG files available on request), original transparency or negative so the judges can check any adjustments comply with the rules. If you cannot supply these, your entry will be withdrawn from the competition.
If you provide an original transparency or negative, we may keep it until October 2023. If you're not successful, your transparency or negative will be returned to you by May 2023.
Unless DNG is the native RAW format of your camera, DNG files will not be accepted as we will be unable to check if any digital adjustments made fall within the competition rules. However, if you have embedded the original RAW in the DNG during the conversion process, you'll be able to extract it and submit it as proof of authenticity.
You will also need to supply a high-resolution file suited to printing in all media. A TIFF file is preferred.
This should be 8-bit, Adobe RGB (1998) at full resolution. Please do not upscale.
