At the occasion of the 24th Weeks of the Photography, the organisation (PCP) invites the amateur and professional photographers, of whatever nationality, to participate to its international photo competition with the general theme «Biodiversity». The photo competition will result in an exhibition at the Espace des Arts in Les Pavillons-sous-Bois 93320, France, during the 24rd edition, which will be held from 4 to 19 October 2025. The target of this competition is to use the photography as pedagogic and visual support to take in account the biodiversity and to promote the commitment in favour of the environment protection.
