Jacques-Henri Lartigue : A Delage Racer at the Grand Prix, 1912 |
Early In the 20th Century, the public was introduced to a new dimension in journalism: action news pictures made with the high-speed, single-lens reflex camera. The first real "press" camera, it was portable, its fast lens and focalplane shutter could freeze even a speedinq car, it tocusedeasily through the taking lens, and its large picture size allowed the high-quality prints needed for engraving. For nearly half a century many of the most memorable news photographs were taken with the German lCA or its neartwin, the American Graflex.
The versatility of the big reflex made it equally popular with photographers who were not journalists. It capitalized on odd distortions in the pictures caused by the focal-plane shutter. In the photograph at rig,ht by J.H. Lartigue, the impression of speed is conveyed by the apparent forward lean of the car's wheel and the backward lean of the spectators. Both effects are due to the shutter, a fast-moving slit that moves vertically across the film, exposing different parts of it at different instants in time. Thus, in taking a picture of a fast-moving car, the bottom of the wheel will be photographed at one point, but when the slit in the shutter reaches the top of the wheel, the whole car will have moved to the right, so that the wheel comes out looking eggshaped. In taking this picture lartigue had to move his camera to keep pace with the car's movement This,in turn, gave the spectators their odd appearance, for when the shutter's slit passed across their legs the camera was in one position, but by the time it exposed their heads the camera and film had moved to the right.
