This book by photographer Matias Costa, co-published with the regional government of Madrid, shows a very wide selection of images from several decades of career and personal documents that define his nomadic and investigative character. A publication in which he weaves his own biography through scenes, objects and characters photographed together with his workbooks and personal notes, diverse contexts that he universalises thanks to his status as a chronicler, visitor and migrant. His photography is both a window and a mirror, inviting us to look and reflect in a world driven by memory and chance. The writers Leila Guerriero and Federica Chiocchetti and the curator Carlos Martin depict in their texts the inseparable life and work of this essential photographer. Matias Costa was born in Buenos Aires (1973) and arrived in Spain in 1977, escaping from the dictatorship. He graduated in Information Sciences from the UCM and began to take photographs in 1989 in a self-taught way. He was the founder and member of the NOPHOTO collective until 2012. In his projects he reflects on migration and memory. Among them are When we are all rich, Cargo, Zonians or The Family Project. He has received, among other important recognitions, the World Press Photo in 2000 and 2002, and the Banca March International Photography Award in 2017. 255 images
