Distortion

Distortion is a term used in photography and cinematography to describe the effect of distorting an image. This effect occurs due to incorrect use of camera optics or lenses, as well as incorrect exposure or white balance settings.

Distortion can be either positive or negative. Positive distortion gives the image a more realistic appearance, making it appear more three-dimensional and vibrant. Negative distortion, on the contrary, makes the image flatter and unrealistic.

Various methods can be used to correct distortion, such as using special lenses or cameras, adjusting exposure and white balance, and using image processing software.

In photography, distortion is used to create certain effects, such as distorting perspective or creating the effect of depth of field. In cinema, distortion is also used to create various effects, such as to create the effect of camera movement or to create the effect of speeding up or slowing down time.

Thus, distortion is an important effect for photography and cinematography, which can be used to create various effects and give the image more realism and depth.

Distortion in technology is the distortion of an image according to some principle, usually radial (or centered at one of the points in the frame). Sometimes in the compressor parameters you can set the value of the distortion position, but this is necessary for non-standard work with sound effects.
