Aliasing  is a form of distortion that occurs when two elements of the signal being processed to form a digital image become indistinguishable from one another. Aliasing often appears in an image in the form of moiré or false coloring.

Moire is a visual perception that occurs when viewing a set of lines or dots that is superimposed on another set of lines or dots, where the sets differ in relative size, angle, or spacing]]> 2019-08-26 18:35:52 UTC https://padlet.com/abbychergosky/vocab1/wish/377230323 abbychergosky https://padlet.com/abbychergosky/vocab1/wish/377230561 are the unwanted side-effects of processing an image.

Wide-angle prime lenses such as a 20mm lens or zoom lenses like my Nikon 24-70mm shot at its wide end typically produce images with barrel distortion because they have a wide field of view.
