The book that named an entire philosophy of photography. Cartier-Bresson’s idea that there is a moment when the visual and emotional elements of a scene align — and that the photographer’s task is to seize it — has been both celebrated and contested for seven decades. The photographs themselves remain staggering: geometry and life caught in perfect tension. The original edition, with its Matisse cover, is one of the most sought-after photobooks ever made. Reading it now, I’m struck by how much trust it places in the world to offer up meaning, if only you’re paying attention.
