When the revolution of 25 April 1974 swept through Portugal, Luiz Carvalho had no idea it would shape the course of his life. Then a 19-year-old architecture student with a passion for photography, he took to the streets of Lisbon with his Nikon F, capturing the unfolding scenes of a country in transformation.
Those early images marked the beginning of a career that would span more than two decades, working for the weekly Expresso and as a correspondent for SIPA Press.
