Photographer by love and by profession, but also advertising designer, journalist, critic and polemicist, exhibition curator, university teacher and historian: through photography, its history, its daily practice, its protagonists and new trends, Colombo took part in the history of Italy. "The centre of my artistic and cultural interests has always been the human condition: my fellow men, the private and social scene around me." Guided by Simona Guerra, he retraces the years, the discussions with friends and colleagues, his most incisive images and some of his writings: the path of "a man who believes in photography as a powerful social and political weapon of our time". The book is organised by decades, from the 1950s to the 2000s, each divided into three sections: Diary, from long interviews; Gazes, his pictures; and Pre-texts, a selection of his writings.
