Rio Branco was a freelance photographer and director of photography for movies when he embarked on documentary photography and was soon noticed for the dramatic quality of his color work. In 1980, he became an associate with Magnum Photos. Fascinated by places of strong contrast, in the power of tropical colors and light, he made Brazil his main area of exploration. In 1985, he published Dulce Sudor Amargo, a book in which he drew a parallel between the sensual, vital side of Salvador da Bahia and the historical side of the city, which, at the time (1979) was inhabited by prostitutes and the fringe elements of society. It is an essay on life and death, on the scars left behind by time and by living. The photographer’s fascination for these places of strong contrast essentially resides in the power of the tropical colors and light, which he conveys by means of his pictorial sensibility.
