Depth of focus
The range of sharpness in front of and behind the film plane in the camera.
The range through which a photographic film can be moved forward or backward with respect to the lens while retaining satisfactory sharp focus on an object at a given distance.
Very important with respect to optical film printers. Can be increased by ‘stopping down’ the aperture.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
