Perspective control is a procedure for composing or editing photographs to better conform with the commonly accepted distortions in constructed perspective. The control would: make all lines that are vertical in reality vertical in the image. This includes columns, vertical edges of walls and lampposts. This is a commonly accepted distortion in ...
The 1961 35 mm f / 3.5 PC-Nikkor lens—the first perspective-control lens for a 35 mm camera. In photography, a perspective-control lens allows the photographer to control the appearance of perspective in the image; the lens can be moved parallel to the film or sensor, providing the equivalent of corresponding view camera movements.
Perspective distortion. Simulation showing how adjusting the angle of view of a camera, while varying the camera's distance and keeping the object in frame, results in vastly differing images. At narrow angles and long distances, light rays are nearly parallel, resulting in a "flattened" image. At wide angles and short distances, objects appear ...
The sensor plane, the lens plane and the plane along the train all intersect to the right of the camera. A scientific camera with a Scheimpflug adaptor mounted between the lens and the camera, showing in stop-motion the potential movements the adaptor provides in the two axes (tilt and swing). The Scheimpflug principle is a description of the ...
Texture mapping. Mapping a two-dimensional texture onto a 3D model. 1: 3D model without textures. 2: Same model with textures. Texture mapping[1][2][3] is a method for mapping a texture on a computer-generated graphic. "Texture" in this context can be high frequency detail, surface texture, or color.
Perspective control: original (left), perspective distortion removed (right). Some image editors allow the user to distort (or "transform") the shape of an image. While this might also be useful for special effects, it is the preferred method of correcting the typical perspective distortion that results from photographs being taken at an ...
This effect can be controlled by using a perspective control lens, or corrected in post-processing. Due to perspective, cameras image a cube as a square frustum (a truncated pyramid, with trapezoidal sides) – the far end is smaller than the near end. This creates perspective, and the rate at which this scaling happens (how quickly more ...
Angle of view (photography) A camera's angle of view can be measured horizontally, vertically, or diagonally. In photography, angle of view (AOV) [1] describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from ...
