beeldvervorming

Beeldvervorming, Dutch for image distortion, refers to the alteration of an image's shape or form from its original state. This can occur through various means, both intentional and unintentional. In photography and optics, lens distortion is a common cause. Barrel distortion makes straight lines appear to bulge outwards, often seen in wide-angle lenses, while pincushion distortion causes them to bend inwards, typically associated with telephoto lenses. Chromatic aberration is another optical distortion where colors fail to converge at a single point, resulting in fringed halos around objects.

Digital image processing can also introduce or correct beeldvervorming. Geometric transformations can resize, rotate, or shear an image, leading to distortion. Perspective distortion occurs when an object appears smaller or larger depending on its distance from the viewer or camera. Conversely, image editing software can be used to deliberately distort images for artistic effect or to correct unwanted distortions introduced by cameras or other devices.

In the context of visual perception, "beeldvervorming" can also describe how the human brain interprets visual information, leading to illusions or misperceptions of size, shape, or distance. These perceptual distortions are a fascinating area of study in psychology and neuroscience, exploring the complex mechanisms by which we construct our visual reality.
