Large-format drawings show portions of the primitive forest in Costa Rica. Made from photographs taken by the writer Julien Burri, the illustrations are produced from the projection of the photographic image on the paper support. The process is based on a technique borrowed from analog photographic printing, through the use of a matrix (here, the negative is replaced by a photocopy, a positive image, partially altered), which allows an enlarged reproduction of the photographic subject, made possible by the use of an overhead projector.
