An Introduction to Photography Techniques: Tilt-Shift
Tilt shift is a photography technique that makes a part of the photo appear as a miniature. This technique is most effective when the photo is taken from an aerial view.
Tilt shift uses the Scheimpflug Principle:
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. 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.
How Tilt Shift Works Manually
(a) Keeping the camera level, with an ordinary lens, captures only the bottom portion of the building.
(b) Tilting the camera upwards results in perspective distortion.
(c) Shifting the lens upwards results in a picture of the entire subject without perspective distortion.
