I'm looking for more information regarding a specific type of visual effect that I have been trying to recreate many times in Photoshop, without any success. I would like to learn how to do this from tutorials, that is if I knew what to search for.
Below I have an image from an Oculus Rift game, and another from a movie trailer (Kung Fury). Notice how light at the edges of objects diffuses into two, sometimes three slight red green and blue colors (RGB). What is this effect called? Obviously the examples are very not alike but the result is pretty much the same thing, and I really want to learn how to accomplish this in Photoshop.
Sorry if the question looks kinda dumb, but I knew no other place where I could ask this.
