Deep Focus
Keeping every plane from nearest foreground to far distance equally sharp by maximizing depth of field.
Deep focus is the photographic rendering of a scene in sharp focus from the nearest foreground to the far distance, so that near, middle, and distant planes appear equally clear. The term is most closely associated with cinema, where it became attached to Gregg Toland's camerawork for Citizen Kane (1941), but the practice in still photography is older. Late nineteenth-century photographers debated whether pictures should record detail with uniform clarity or, as Peter Henry Emerson argued, keep only the main subject sharp in imitation of human vision. In 1932, Group f/64, whose members included Edward Weston and Ansel Adams, took its name from the smallest aperture of large-format view cameras, chosen for the greatest depth of field, in a break with the soft-focus Pictorialism then prevalent on the West Coast.
Depth of field increases as the aperture is stopped down, as focal length shortens, and as the camera moves farther from the subject. Photographers seeking deep focus therefore favor small apertures, wide-angle lenses, and focusing at the hyperfocal distance, and the long exposures that small apertures require suit still subjects such as landscape, architecture, and still life. On view cameras, tilting the lens or film standard according to the Scheimpflug principle aligns the plane of focus with a receding ground or façade, extending sharpness without relying on aperture alone. Very small apertures also soften fine detail through diffraction, and digital focus stacking avoids this by merging frames focused at different distances into one image. Bernd Becher and Hilla Becher used large-format cameras to describe industrial structures with sharp focus, fine detail, and wide depth of field, maximizing the information each print carries.
Deep focus is usually contrasted with Selective Focus, which isolates one plane and lets the rest dissolve into blur, and with Soft Focus, which diffuses the whole image rather than limiting sharpness to a zone. It is closely tied to Straight Photography, whose advocates held that the camera could see more clearly than the eye, a claim at odds with Emerson's view that human sight rarely holds anything fully in focus. Digitally assembled pictures such as Andreas Gursky's have reopened the question, as critics observe that they register more detail, and hold it in sharper focus, than human vision allows.
