Francisco Márquez, Isabel Juárez and Jesús Rodríguez traveled to the Balkans in northern Greece to start filming a short documentary about Prespa National Park. This is a commission we have received from a prestigious Greek conservation organization to make a promotional video of this extraordinary natural site, where several thousands of Dalmatian pelicans reproduce. Shooting will show the biodiversity of the park and the main human activities more sustainable with the environment.
