distorting

Distorting refers to the act of changing something from its original form, shape, or meaning. Distortion is the result of such alteration. The term spans multiple disciplines and everyday usage, often indicating deviation from truth, accuracy, or intended representation.

In physical and technical contexts, distortion can be optical, geometric, or electronic. Optical distortion occurs when a lens or optical system causes image shapes to bend from their true geometry, producing effects such as barrel or pincushion distortion. Geometric distortion in imaging can also arise from sensor or processing issues. In electronics and acoustics, signal distortion refers to deviations from the original waveform, often due to nonlinear processing, clipping, or intermodulation; total harmonic distortion is a common quantitative measure. In audio, distortion is sometimes an intentional effect to alter timbre.

In media, journalism, or data transmission, distortion denotes misrepresentation or alteration of information or signals, whether deliberate or accidental. In cartography, map distortion reflects the challenge of representing a curved surface on a flat plane, affecting scale, angle, or area accuracy.

In psychology, cognitive distortions are patterns of thinking that are biased or irrational, affecting perception and decision-making.

Mitigation and analysis often involve calibration, correction algorithms, or modeling to reduce distortion, or to compensate for it, such as lens correction in photography, pre-distortion in communications, or deconvolution in signal processing.

Etymology: distorting comes from Latin distortus, from distorquere, meaning to turn aside or twist.
