Perspective control is a procedure for composing or editing photographs to better conform with the commonly accepted distortions in constructed perspective. The control would: The control would: make all lines that are vertical in reality vertical in the image.
Also may mean "Perspective Control" for a lens that has the ability to shift to tilt to control linear perspective in an image. May also stand for personal computer in conjunction with digital photography. PDAF: Phase-detection autofocus. One of the mechanisms of automatic lens focusing. PF: Purple fringing. A form of chromatic aberration in ...
A darkroom is used to process photographic film, make prints and carry out other associated tasks. It is a room that can be made completely dark to allow the processing of light -sensitive photographic materials, including film and photographic paper .
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.
Darkroom manipulation is a traditional method of manipulating photographs without the use of computers. Some of the common techniques for darkroom manipulation are dodging, burning , and masking , which though similar conceptually to digital manipulations, involve physical rather than virtual techniques.
Unsharp masking (USM) is an image sharpening technique, first implemented in darkroom photography, but now commonly used in digital image processing software. Its name derives from the fact that the technique uses a blurred, or "unsharp", negative image to create a mask of the original image. The unsharp mask is then combined with the original ...
Hugin (/ ˈ h ʊ ɡ ɪ n /) is a cross-platform open source panorama photo stitching and HDR merging program developed by Pablo d'Angelo and others. It is a GUI front-end for Helmut Dersch's Panorama Tools and Andrew Mihal's Enblend and Enfuse.
The weak-perspective model thus approximates perspective projection while using a simpler model, similar to the pure (unscaled) orthographic perspective. It is a reasonable approximation when the depth of the object along the line of sight is small compared to the distance from the camera, and the field of view is small.
