La salle, de douze m\u00e8tres de diam\u00e8tre, contenait trois cent cinquante places. Par rotation, la salle venait se placer devant une ouverture de 7,5 m de large et 6,5 m de haut, faisant office d\u2019avant-sc\u00e8ne et dont les cot\u00e9s allaient en s\u2019\u00e9vasant jusqu\u2019au fameux tableau peint sur les deux faces qui mesurait 14 m de haut sur 22 m de large. C\u2019est alors que le spectacle commen\u00e7ait. Au-del\u00e0 du tableau, de grands ch\u00e2ssis vitr\u00e9s permettaient l\u2019\u00e9clairage par derri\u00e8re ou par transparence, tandis que d\u2019autres ch\u00e2ssis donnaient, depuis les combles, un \u00e9clairage par le haut et par le devant. En interposant devant ces ch\u00e2ssis des panneaux translucides teints de diff\u00e9rentes couleurs et actionn\u00e9s par des cordages, on pouvait changer la tonalit\u00e9 g\u00e9n\u00e9rale ou locale du tableau, permettant ainsi de produire sur le tableau entier, ou en quelques points, des effets allant du brouillard intense au soleil \u00e9clatant. <\/p>\n<\/div><\/div>\n\n<\/div><\/div>\n\n\n<p class=\"wp-block-paragraph\">Le spectacle durait environ quinze minutes, apr\u00e8s quoi la salle entrait \u00e0 nouveau en rotation et venait progressivement se placer devant une nouvelle ouverture identique \u00e0 la pr\u00e9c\u00e9dente, pratiqu\u00e9e dans la circonf\u00e9rence de la salle. Un nouveau tableau se pr\u00e9sentait \u00e0 la vue des spectateurs et un nouveau quart d\u2019heure d\u2019animation par des jeux de lumi\u00e8re pouvait commencer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En d\u00e9cembre 1827, Daguerre fera la rencontre de Ni\u00e9pce alors de passage \u00e0 Paris avant de se rendre en Angleterre. Les deux hommes s\u2019appr\u00e9cieront mutuellement. Ni\u00e9pce sera fascin\u00e9 par le Diorama. Daguerre avait eu lui aussi l\u2019id\u00e9e de capter les images de la chambre obscure. Pour cela, il disposait des poudres phosphorescentes au fond de sa chambre obscure. L\u2019image projet\u00e9e sur cette poudre y demeurait ensuite visible pendant plusieurs heures avant de d\u2019estomper peu \u00e0 peu. Les deux hommes se reverront lors du retour d\u2019Angleterre de Ni\u00e9pce en f\u00e9vrier 1828.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ils commenceront ensuite \u00e0 \u00e9changer des id\u00e9es par courrier et en 1829, Ni\u00e9pce offrira \u00e0 Daguerre de former une association pour contribuer au d\u00e9veloppement de l\u2019invention de l\u2019h\u00e9liographie. Le contrat d\u2019association sign\u00e9 en d\u00e9cembre 1829, Daguerre s\u2019attachera \u00e0 travailler sur le proc\u00e9d\u00e9. Il apportera un contribution importante puisque les deux hommes inventeront en 1832 un nouveau proc\u00e9d\u00e9 : le physautotype. Apr\u00e8s la mort de Ni\u00e9pce, Daguerre poursuivra seul les recherches sur la capture des images et inventera le daguerr\u00e9otype, proc\u00e9d\u00e9 photographique dont la pratique devenait plus ais\u00e9 puisque le temps de pose n\u2019\u00e9tait plus que de quelques minutes. Le daguerrotype conna\u00eetra un immense engouement et Daguerre conna\u00eetra la c\u00e9l\u00e9brit\u00e9 dans le monde entier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Apr\u00e8s s\u2019\u00eatre retir\u00e9 \u00e0 Bry-sur-Marne, Daguerre mourra le 11 juillet 1851.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/speos-photo.com\/fr\/\" target=\"_blank\" rel=\"noopener\">&gt; D\u00e9couvrir Sp\u00e9os, l&rsquo;\u00e9cole de photographie qui finance la Maison Ni\u00e9pce<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Louis Jacques Mand\u00e9 Daguerre (1787-1851) \u00e9tait peintre et d\u00e9corateur de th\u00e9\u00e2tre.
