From Wikipedia, the free encyclopedia

Tilt-shift photography is an artistic technique where the lens is tilted and shifted relative to the attached camera.

[edit] Applying the Technique

On early cameras, the two are connected by a bellows. When tilt is applied, the film or image sensor is not at a right angle to the optical axis of the lens, causing a gradient of focus. The technique can also be done with a modern camera by constructing a tilted lens manually. Dennison Betram, who built his own tilt-shift lens, noted that the lens used should be one intended for a larger film format than the camera, so that vignetting doesn't occur as the lens is tilted.

[edit] Uses of effect

By blurring, the viewer's gaze may be directed away from parts of the image the photographer wishes to de-emphasize.

A smaller depth of field can also be simulated by bringing the foreground and/or background out of focus.

Perspective can be corrected for by sharpening the focus of a foreground and background that would otherwise be outside the depth of field; in theory, perfect perspective correction happens when the planes of the lens, the image sensor, and the object being imaged all intersect. [1]

[edit] Miniature faking

Main article: tilt-shift miniature faking

Miniature faking, in which the location in the photograph appears to have been created in miniature, can be done using the technique. This was popular in the early years of the twenty-first century.^[1]
