Spring Daffodils beside ancient fortifications. Tilt and shift mechanisms on large format cameras remove distortions from converging verticals and by adjusting that the plane of focus maintains sharpness throughout the image.
The Scheimpflug principle is a geometric rule that describes the orientation of the plane of focus of an optical system (such as a camera) when the lens plane is not parallel to the image plane. It is commonly applied to the use of camera movements on a view camera ( Images 2, 3). It is also the principle used in corneal pachymetry, the mapping of corneal topography, done prior to refractive eye surgery such as LASIK, and used for early detection of keratoconus. The principle is named after Austrian army Captain Theodor Scheimpflug, who used it in devising a systematic method and apparatus for correcting perspective distortion in aerial photographs.
Both Canon ( tilt shift macro lens series) , Nikon ( pc micro Nikkor series ) and Leica ( Leica R ( PC-Super-Angulon-R 28mm f/2.8 ) and Medium format Leica S ( TS-APO- Elmar-S 120 f/5.6 ASPH ) have made lenses for digital cameras that effectively incorporate front tilt and shift.
