Sixteen chapters in the form of personal incursions into the history of the medium: thoughts and reflections, the study of thousands of frames by makers famous and unknown, a rereading of the key volumes and the most illuminating essays. Together they tell the evolution of the style of an art through Kertész, Capa, Cartier-Bresson, Doisneau, Giacomelli and Ghirri, who as brilliant and poetic pioneers told the century.
