Slide background




The Underwater Photo Marathon is an online based competition. The participants of the annual competition need to send their photos in a given time period to the organizer. After the time window expires a jury of experts elects the winners.



Submissions are accepted from photographers worldwide, as long as they're taken with a digital camera. All are welcome to enter the competition, amateurs and professionals alike.





The photos have to be submitted through the official website. The results will be posted on the same website upon jury's decision. The award ceremony will follow at the Underwater Photo Marathon exhibition opening, and the best photos will also be displayed virtually.




Because we are a young and enthusiastic team from the diving club "Roniti se mora", focused on the goal to improve the cultural offerings of the city of Zagreb, by providing a different perspective on photography. And why a marathon? Our ultimate goal is to display the best photos year round on an exhibition in various institutions in Zagreb as well as country wide, until the next competition which marks the beginning of a new cycle. That way the concept of underwater photography becomes available to a number of people of different backgrounds, which allows for it to continuously promote itself.
