Afin d'illustrer ces résultats scientifiques, le photographe Gaëtan Bally a réalisé des comparaisons fascinantes : à côté de l'image normale de la scène, une photo infrarouge rend visibles les températures de surface. Cette visualisation ne repose pas sur un simple filtre, mais sur une véritable technique de mesure : une caméra thermique capte le rayonnement infrarouge des surfaces, qui est ensuite traduit en un spectre de couleurs. Ainsi, les parcs et les plans d’eau se parent d’un bleu frais, tandis que l’asphalte ou les façades fortement chauffés apparaissent en rouge vif.\u003C\u002Fp>","under","NULL",[61],{"links_id":62},{"id":63,"anchor":3,"label":64,"color":65,"type":66,"link_external":67,"link_email":3,"link_phone":3,"link_page":68,"link_asset":3},"25965db3-b193-48c4-b7b5-8e6f1972bf20","Catalogue d’images Keystone","red","external","https:\u002F\u002Fvisual.keystone-sda.ch\u002Flightbox\u002F-\u002Flightbox\u002Fpage\u002F2426048\u002F1",[],{"collection":23,"item":38,"id":39,"data":70},{"id":38,"anchor":3,"title":3,"introduction":3,"text":71,"button_position":58,"media_type":59,"media_position":3,"youtube_url":3,"image":3,"button":72},"\u003Cp>\u003Cimg src=\"https:\u002F\u002Fenergie-cluster.ch\u002Fassets\u002Fc1f1b9f3-64a1-42b2-b01d-e4ce0b25659f\" alt=\"\">(Image : Keystone)\u003C\u002Fp>",[],[74],{"id":43,"translations":75},[76,77],{"name":46,"languages_code":20},{"name":48,"languages_code":32}]
