All photographers over 18 years of age, regardless of nationality or residence, are eligible to participate in the Competition, provided they register online as outlined in the rules. The theme is open, although preference will be given to images that, within the photographer's creative freedom, offer fresh perspectives on the cultural, monumental, natural, environmental, landscape, human, and intangible richness of the territories comprising the EUROACE Euroregion. Images must be taken within the EUROACE Euroregion, which includes the Alentejo and Centro Regions (Portugal) and the Autonomous Community of Extremadura (Spain). Photographs in black and white or color, both digital and analog, at high resolution (minimum 300 dpi) will be accepted. Each photographer may submit a maximum of two works. Works that have won prizes in other competitions will not be accepted, although those that have only been previously selected will be. Works generated by artificial intelligence will also not be accepted.
