Published in 1963 in the Cadernos Brasileiros series, in collaboration with the poet Thiago de Mello, this was Sergio Larrain’s very first publication and soon became a seminal work for Chilean and Latin American photography. In 44 pages it shows the photographer’s vision of photography, and for the first time he considered his work from a theoretical standpoint: “rectangle in hand (the camera), I seek geometry”. This facsimile of the original, with an essay by Agnès Sire, pays tribute to the emblematic book.
