"In photography, distortion is generally referred to an optical aberration that deforms and bends physically straight lines and makes them appear curvy in images, which is why such distortion is also commonly referred to as “curvilinear” (more on this below). Optical distortion occurs as a result of optical design, … See more Some lenses are optically designed to be “rectilinear” (like the Nikon 14mm f/2.8D and the Canon EF 14mm f/2.8L II USM), where they yield … See more So far we have been only talking about optical distortions. Another distortion type that is often seen in images is perspective distortion. Unlike optical distortion, it has nothing to do with lens optics and thus, it is not a lens error. … See more " - Photographic distortion

What is Lens Distortion? Barrel vs Pincushion Distortion - Aperlust

In photography and cinematography, perspective distortion is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal focal length, due to the relative scale of nearby and distant features. Perspective distortion is determined by the relative distances at which the image is captured and viewed, and is due to the angle of view of the image (as captured) being either wider or narrower than the angl… Although distortion can be irregular or follow many patterns, the most commonly encountered distortions are radially symmetric, or approximately so, arising from the symmetry of a photographic lens. These radial distortions can usually be classified as either barrel distortions or pincushion distortions. Barrel distortion In barrel distortion, image magnification decreases with dista… Although distortion can be irregular or follow many patterns, the most commonly encountered distortions are radially symmetric, or approximately so, arising from the symmetry of a photographic lens.

WebMar 16, 2024 · Photographic distortion can be divided into two categories: perspective distortion and optical (lens) distortion. Any deformation that occurs in the images created by a camera lens is lens distortion. In general, lens distortion can be defined as when straight lines in photographs appear bent or curved. WebDistortion commonly occurs from aberrations near the edges of an image. Each type of distortion usually develops through different variables. Barrel distortion, for example, is often the result of a lens at full zoom, while pincushion distortion occurs most often from telephoto lenses.
