These two photographs are examples of scenes that were sharply focused using the Scheimpflug principle (Figs. The limitation is when vertical structures (tree trunks, tall flowers) extend above the wedge of focused reality and can’t be focused by tilting the lens and keeping the ground plane in focus at the same time. What’s created is a wedge of focused reality that’s projected out from the camera, creating an illusion of great depth of field. To the landscape photographer, this means if the lens is tilted forward an appropriate distance, you can adjust the plane of focus to run parallel to the ground. Theodor Scheimpflug (1865-1911) stated: “If the lens plane is tilted down, when the extended lines from the lens plane, the object plane and the film plane intersect at the same point, the entire subject plane is in focus.” This is the Scheimpflug principle. Historically, photographers relied on two basic techniques to maximize depth of field: using hyperfocal focusing techniques with large ƒ-stops and shifting the plane of the lens so the axis of the lens was no longer perpendicular to both the film plane and a focused slice of reality.Ī conventional lens has the planes of the sensor (or film), the lens and the focused slice of reality all perpendicular to the axis of the lens. The scene was photographed with a 4×5 view camera with a 120mm lens focused and with the lens tilted.ĭepth of field: This has been a concept photographers have grappled with since the advent of the camera.
