what is chromatic aberration in video games

Chromatic aberration is a visual effect that is integrated into video games to induce the feeling of looking through a camera lens. It is a type of color distortion that occurs in lenses, like that on a camera, which causes a red and blue aura either side of objects. Chromatic aberration is a screen-based method that mimics lens distortions and can be utilized to give video game scenes a classic, low-fi, and analog feel or to make it feel more cinematic. It is mainly noticeable in photography and can be seen in various aspects of gameplay, like in corners and sharp edges, when chromatic aberration is turned on. Chromatic aberration is an unwanted feature in photography that occurs due to the refraction of light as it passes through the lens toward the focal plane. In video games, chromatic aberration can make the graphics look less sharp and reduce the overall quality of the image. While some people like chromatic aberration, it is often overused, and many have grown to dislike it.
