Modotti, the textile-worker, has migrated to the USA in 1920, tying to make her way as an actress. She has been acting in several movies made in Hollywood. In 1923, she moved to Mexico together with Edward Weston, photographer, where she became his model and student. She was posing for Diego Rivera and other artists as well. She first exhibited photographs in 1925, Guadalajara, together with Eward Weston, who returned to the United States a year later. Modotti stayed in Mexico. She joined the league of “Hands off Nicaragua”, in 1927 she joined the Mexican Communist Party, and she became a photojournalist of its newspaper, El Machette. She fought on the side of the American Anti-imperialist League. Her works were published in papers entitled Mexican Life and Mexican Folkways. In 1928 she encountered and became companion of the Cuban revolutionary, Julio Antonio Mella. When Mella was killed in 1929, Modotti became subject of a press-offensive. She was accused of being a communist spy. She was arrested in 1930, and after she refused to become the official photographer of the National Gallery, she was deported. By this time, she has become a photographer of international fame. Following the period inspired by Weston, she turned more and more towards the true problems of the society. Her revolutionary period has started, in which she was capturing the Mexico of her time, as she would put it: ”without taking photographs of colonial churches, the breaking of wild horses, the folk-ware of the Pueblas and similar trash, as many photographers did.” She founded a school in the art of Mexican photography, and her influence is recognisable today. She joined the Unionfoto professional league in Berlin, and the German Communist Party. In 1930 she travelled to the Soviet Union, but she refused the offer of the Soviet Communist Party to take part in the works of the first five-year-plan as a photographer. “I cannot take pictures, where there is so much to be done.” She worked for the International Red Aid, she carried out several secret missions in different European countries. In 1936, at the victory of the National Front, she moved to Spain and organised a nursery league. During the fall of the republicans, she returned to Mexico, through France with a fake passport. Lázaro Cárdenas, Mexican president annulled the order of expulsion, which was still valid against her. In Mexico, among others she was working for El Popular, contributing to the organisation of the Giuseppe Garibaldi Antifashist League, and she once again returned to photography.
