This slide piqued my interest because I recall seeing a post-processing effect called chromatic aberration. It's interesting to know that, although lens aberration decreases the quality of an image, aberration is sometimes intentionally added in software for artistic purposes. Here's the Wikiapedia page (https://en.wikipedia.org/wiki/Chromatic_aberration), as well as an examples of how aberration might be used artistically in practice (https://docs.unity3d.com/560/Documentation/Manual/PostProcessing-ChromaticAberration.html).
