MARE 2025 COMPETITION
The sixth edition of MARE will follow the classic contest format, with underwater digital photography as the main discipline. Photography is an ideal language to reveal the hidden beauty of the sea, with all its colours and light. It also allows us to document species and habitats, providing essential information about their conservation status.

VI EDITION SUMMARY
Open call for entries for the MARE 2025 Audiovisual Competition for the Conservation of the Balearic Sea
Deadline for submitting your photographs: 15 September 2025.
You can submit up to 20 digital photographs related to the Balearic and Mediterranean seas, which bring to light their richness and beauty or show the relationship between people and the marine environment, be they positive or negative relationships, success stories, or complaints.
In all cases, the photographs must have been taken in the Balearic or Mediterranean seas since October 2019 and must not have been awarded a prize in any of the previous MARE competitions.
Those under 16 years of age can participate in the YOUTH DIVISION and those aged 16 and over in the GENERAL DIVISION. Depending on their experience, those in the GENERAL DIVISION can participate as an AMATEUR (original JPG or RAW essential) or an EXPERT (RAW essential).
If you are participating in the YOUTH DIVISION, you can submit your photographs to a single, generic, juried category. You are also eligible to submit to MARE Popularis.
If you are participating in the GENERAL DIVISION, you can submit your photographs across any or all of the five juried categories: 1. MARE Animalia; 2. MARE Botanica; 3. MARE Sapiens; 4. MARE Denuntiare; 5. MARE Nostrum. You are also eligible to submit to MARE Popularis.
In the MARE Popularis (People’s Choice) category, open to all participants, the winner will be chosen by popular decision through your votes on our website.
All photographs must be submitted in JPG format, with 1920 pixels on the largest side and less than 4 MB in size, without watermarks, borders, or captions.
Each photograph you submit must be accompanied by a short conservation text. Also, you must indicate where it was taken, the approximate date and its title.
Except for MARE Popularis, the jury will select the most interesting photographs in each category and award the prizes.
A total of €10,000 will be distributed over 24 prizes in the form of cash and Aquatic Expedition Kits. Six honourable mentions will be awarded: three for «marine protected areas» and three for «shallow bays».
The selected photographs will be included on our website and may form part of a travelling exhibition that will tour the Balearic Islands in 2026.
Registration for MARE 2025 is free for those under 18 years old, members of the Associació de Fotografia de Natura de les Illes Balears (AFONIB), the Federación Balear de Actividades Subacuáticas (FBDAS), flickerosdeibiza and associated diving centres.

ETHICAL CODE
The audiovisual competition for the conservation of the Balearic Sea is subject to the code of ethics that regulates conservation photography, which all participants must respect and comply with. The spirit of this code of ethics focuses, above all, on these principles:
- The safety of the subject and the preservation of its environment is always more important than obtaining the photograph.
- The biology and behaviour of the species to be photographed must be documented beforehand to prevent inappropriate actions.
- The necessary permits must be requested from the relevant authorities to photograph species that require this by law or are in protected areas.
- Animals must be photographed in their natural environment, with no alteration to their behaviour.
- The location of rare or endangered species should not be disclosed, except to accredited researchers and administrations responsible for their conservation.

Digital processing of photographs is not only permitted, but often recommended. The photo should be as true to reality as possible. You can adjust your photo, but you cannot create something new or delete something that exists. You can do adjust the white balance, make level adjustments, reframe, adjust the contrast and saturation, remove spots from the sensor, and so on. You can’t clone, delete, distort dimensions, transform perspective, over-process, overlay, or make double exposures that have not been made in-camera. Photographs submitted to MARE Popularis are not required to meet this criterion.

You can submit your processed photographs as long as they are true to life. If your photo is shortlisted, we will ask you for the original file (either RAW or JPG, whichever your camera stores) to check that any photo editing is within the allowed parameters.
-
Yes, you can. There is only one condition. The cropped file you have on your computer (not the one you send us to participate, but the original) must weigh at least 10 megabytes without interpolation. If your photograph is selected, we will need a high-quality file to make physical prints for the exhibition.

-
What the entry tool shows you when you upload your photo is a thumbnail of it; it is not your photo. It is a very low-quality rendition of your photo that is only intended to confirm that you have uploaded the correct one. Don't worry, the jury will see the photo you see on your screen.
-
Have your monitor properly calibrated and to submit your photo with an Adobe RGB 1998 colour profile.
-
It is not mandatory, but it is recommended. The Adobe RGB 1998 colour profile creates a space that encompasses most of the colours that can be printed on a CMYK printer without conversion. This gives us a minimum level of quality that allows us to ensure that we will see your photo as you see it on your computer. Higher colour spaces such as ProPhotoRGB are also allowed.

-
Format: JPG. Size: 1920 pixels on the larger side. Maximum weight: 4 Megabytes. Colour space: Adobe RGB 1998 (recommended, not mandatory). Do not remove the Exif (shooting parameters of the photograph). No watermarks, borders, or captions.
-
Sure! Open your photo with any photo editing program. Open dimensions/photo size or some similar command and type 1920 ppx on the side with the largest number. The size of the other side (the smallest) should change automatically. If it hasn't changed, look on the screen next to those numbers for a picture of a paper clip. Click on it to have the proportions automatically adjusted. Save this file in Adobe RGB 1998 colour profile (this is recommended but not mandatory). Click on ‘Save file as jpg’ and change the compression rate until it is less than 4 Megabytes.
-
There are free online programs that allow you to do this. One that works quite well is https://www.adobe.com/es/express/feature/image/resize. You only have to register, but it is free forever.
