L’atelier de Kallitypie avec N\u00e9gatifs Num\u00e9riques<\/strong> se centre sur l\u2019apprentissage de cette technique d\u2019impression par contact, bas\u00e9e sur des sels ferriques et d\u2019argent, d\u00e9velopp\u00e9e en 1889 par le chimiste et photographe \u00e9cossais W.W.J. Nicols.<\/p>\n

Cette technique se distingue par sa large gamme tonale et la capacit\u00e9 de capturer les d\u00e9tails dans les zones d\u2019ombre. Un aspect fondamental de l\u2019atelier est le calibrage des n\u00e9gatifs num\u00e9riques, n\u00e9cessaire pour obtenir des tirages avec des proc\u00e9d\u00e9s historiques qui correspondent fid\u00e8lement \u00e0 l\u2019image num\u00e9rique originale. Comme la courbe des tons de ces proc\u00e9d\u00e9s n\u2019est pas lin\u00e9aire, il faut ajuster chaque n\u00e9gatif au proc\u00e9d\u00e9 sp\u00e9cifique.<\/p>\n

Joaqu\u00edn Paredes<\/strong> est un photographe sp\u00e9cialis\u00e9 dans les proc\u00e9d\u00e9s historiques.<\/p>\n

Ses projets personnels sont abord\u00e9s \u00e0 travers l\u2019exp\u00e9rimentation avec des techniques du XIXe si\u00e8cle, comme le collodion humide ou les daguerr\u00e9otypes, afin de traiter des sujets contemporains et de revendiquer l\u2019usage de ces proc\u00e9d\u00e9s dans la photographie actuelle.<\/p>\n

Il a expos\u00e9 son travail dans des festivals et revues nationaux et internationaux, tels que la Real Academia de Bellas Artes de San Fernando, C\u00e1ceres de Foto, Revela\u2019t, Segovia Foto, L\u2019\u0153il de la Photographie…<\/p>\n

De plus, il combine ses projets avec l\u2019enseignement pour des institutions comme l\u2019IPCE, le CDIS, l\u2019ICCD (Italie), le Mus\u00e9e San Telmo et l\u2019Acad\u00e9mie d\u2019Espagne \u00e0 Rome.<\/p>\n
