Published in the "Cuadernos Brasileiros" collection, thanks to the Brazilian poet and cultural attaché Thiago de Mello, this book subtly exposes Sergio Larraín's vision of photography in 44 pages. For the first time, Larraín reflects on his work from a theoretical standpoint. This definition, conceived as a syllogism intertwined with a hint of haiku, captures the spirit that animated him at the time, which he later resumes in his books of philosophical reflection.
