What is distortion

Distortion is mainly of two types – barrel-shaped (convex, Barrel distortion) and pillow-shaped (concave, Pincushion distortion). Distortion is usually called simple ‘barrel‘ and ‘pillow‘. But there is also a complex or complex distortion (complex distortion), in which the distortions in different areas of the image have a different type and intensity. Complex distortion is quite difficult to correct with the help of graphic editors, since there the distortion can be waves ’. Professional photographers are affectionately referred to as “camel’, sometimes ‘a double-humped camel‘, as such distortion often gives a kind of visual humps and depressions in the image. In foreign literature, you can find other interesting names for distortion.

‘Fish Eye класса class lenses have very strong barrel distortion, the use of these lenses allows you to create unusual photos in which distortion often plays a key role in creating the desired visual effect. Usually no one corrects the distortion of the Fish Eye lenses. Below is an example of a shot on a Zenitar 16mm F2.8 MC Fisheye lens.
Eye. The curved straight lines of the houses are visible.

The fisheye lens is a wide-angle lens, because it is often used in rooms with limited space.

Due to the fact that distortion is mainly inherent in wide-angle lenses, and wide-angle lenses themselves convey a perspective image in a special way, the distortion effect and a special perspective transfer can give an unusual look to photos:

It is especially difficult to shoot people on ultra wide-angle lenses:

If you do not have a specialized Fisheye lens or a super-wide-angle lens, then the effect of strong distortion can be easily simulated by almost any program-processor. Below, I specifically reinforced the barrel distortion to create a visual effect.

Usually the distortion is easily corrected using software, almost all editors have the ability to compensate for the distortion effect of the lens, just find the Distortion slider and twist it back and forth. However, when compensating for barrel distortion, it is usually necessary to cut off part of the frame, since empty space falls into the image field. Many cameras have the function of automatic distortion correction, while the camera taking into account the parameters of the lens and can most efficiently calibrate the original image.
