A fleeting moment frozen in time, this gelatin silver print by Jacques-Henri Lartigue captures his cousin Bichonnade mid-movement on a staircase at 40 rue Cortambert in Paris. Lartigue's characteristically spontaneous and joyful photographic eye transforms an everyday domestic scene into a dynamic study of motion and elegance. The image reflects his lifelong fascination with capturing the energy and lightness of the world around him, particularly within the intimate circle of his family.
