mt Anamorphic Astigmatism

Anamorphic lenses are becoming increasingly common in all kinds of productions. With them come various lens aberrations, each visually unique and often beautiful, but sometimes difficult to match.

The main ones are astigmatism and coma. Astigmatism creates blur around the edges because light rays converge at different focal planes depending on their orientation. Coma, similarly, produces an asymmetric streak or comet tail.

To make it easy to reproduce, I've created two tools (technically three): Anamorphic Astigmatism and Coma. You will find to different Anamorphic nodes, standard and chroma, wich allows you to distort each channel independently.
