One is an actor, the other is a painter. Almost two generations separate them, yet both men turned to photography after abandoning their respective careers. Discover a double exhibition on the pioneers of documentary photography at the HCB foundation and at the Carnavalet Museum - History of Paris. Eugène Atget's work strongly influenced that of Henri Cartier-Bresson. The latter imitated him for a long time in his way of photographing things. When he discovered the iconic Leica and the "image on the sly", his work took a different direction. He captures moments on the spot; he travels a lot and is passionate about the Man he photographs in the street during walks or meetings. A stroller, the trained painter always carries his camera with him. His predecessor prefers to take his time. Eugène Atget's photographs are calculated, premeditated, thoughtful. More interested in the city than anything else, he photographs Parisian architecture from all angles: from classical monuments to mansions, everything is there! Even if a few characters are present, architecture is indeed the main subject of his pictures. This documentary approach of what surrounds him fascinates his contemporaries and successors. Although their works have ended up distancing themselves from each other, the two men are similar in their behavior: their desire to distance themselves from any academic art form has allowed them to be totally free and independent. A certain poetry can be found in some of their clichés. Anne de Mondenard of the Carnavalet Museum - History of Paris and Agnès Sire of the HCB Foundation have selected the best photographs of the two men from the collections of both institutions.
