The first book of a monographic character about artist Lucia Koch (Porto Alegre, RS, 1996), whose production stands out in the national and international arts. Interventions with filters, glasses, videos and photographs are some of the media that the artist chose to investigate the relationship between light and space, always in dialogue with the architecture of the place where their works are installed. The changes proposed by Lucia not only modify the public's perception of the constructed world, but also their understanding of the lived space and its possibilities of use. The book contains an unpublished text by Dan Cameron, curator of the 13th edition of the Cuenca Biennial (Ecuador, 2016), and an interview with Jochen Volz, director of the São Paulo Pinacoteca and curator of the 32nd São Paulo Biennial, 2016.
