Most large format (4x5 and up) cameras have this feature, as well as plane of focus control built into the camera body in the form of flexible bellows and moveable front (lens) and rear (film holder) elements. Thus any focal length lens mounted on a view camera or field camera, and many press cameras can be used with perspective control.
Example image exhibiting blown-out highlights. Top: original image, bottom: blown-out areas marked red. In digital photography and digital video, clipping is a result of capturing or processing an image where the intensity in a certain area falls outside the minimum and maximum intensity which can be represented.
On a view camera, the tilt and shift movements are inherent in the camera, and many view cameras allow a considerable range of adjustment of both the lens and the camera back. Applying movements on a small- or medium-format camera usually requires a tilt–shift lens or perspective control lens. The former allows tilt, shift, or both; the ...
Single-lens reflex camera. A camera where the same lens is used to view the scene and to focus its image onto a film emulsion or solid-state photosensor. Usually combined with the facility to fit one of a range of lenses, and often more versatile than viewfinder/rangefinder cameras. [11] SOOC: Straight out of camera. Images as shot out of ...
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
Edge-preserving filters are designed to automatically limit the smoothing at “edges” in images measured, e.g., by high gradient magnitudes. For example, the motivation for anisotropic diffusion (also called nonuniform or variable conductance diffusion) is that a Gaussian smoothed image is a single time slice of the solution to the heat ...
The Lens Correction filter in Photoshop can also achieve the same effect. In digital imaging, this technique is used to create a low fidelity appearance in the picture. To give a photo a 'retro' look - that it was made with an old camera or lens - one could add an obvious 'vignette' using 'lens correction' or burning in margins by any of ...
Rotating the lens (as by adjusting the front standard on a view camera) does not alter linear perspective [d] in a planar subject such as the face of a building, but requires a lens with a large image circle to avoid vignetting. Rotating the image plane (as by adjusting the back or rear standard on a view camera) alters perspective (e.g., the ...
