The image of a young couple kissing passionately in a Paris street, oblivious to people walking past, is the most famous of Robert Doisneau’s photographs. Celebrated for his memorable scenes of everyday Parisian life, Doisneau also portrayed miners in northern France, countesses and artists including Picasso. An exhibition of the most striking photographs taken during his long career is in Paris’s Maillol Museum, the biggest Doisneau retrospective in the city for 19 years.
