The concept of perspective distortion has fascinated artists, architects, and scientists for centuries, evolving alongside the development of visual culture and optical theory. Perspective distortion refers to the manipulation of visual perception through deliberate techniques that create altered or exaggerated views of objects or scenes.
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 ...

Picture of Notre Dame de Reims showing perspective distortion The same picture corrected. 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.
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 ...
Isometric video game graphics are graphics employed in video games and pixel art that utilize a parallel projection, but which angle the viewpoint to reveal facets of the environment that would otherwise not be visible from a top-down perspective or side view, thereby producing a three-dimensional effect.
The keystone effect is the apparent distortion of an image caused by projecting it onto an angled surface. It is the distortion of the image dimensions, such as making a square look like a trapezoid, the shape of an architectural keystone, hence the name of the feature. In the typical case of a projector sitting on a table, and looking upwards ...
Beginning in 1967, Dutch artist Jan Dibbets based an entire series of photographic work titled Perspective Corrections on the distortion of reality through perspective anamorphosis. This involved the incorporation of land art into his work, where areas dug out of the Earth formed squares from specific perspectives.
