Creating chromatic aberration

In this tutorial we're going to look at…adding something called chromatic aberration to your optical flares.…Now chromatic aberration is a weird optic phenomenon that happens in…cameras when the lenses and the sensors can't quite line up…all the different wave lengths of color to complete an image…and the way that this shows up in the image is that.…We'll often have, like, maybe, a, a purple fringe.…Or sometimes…a red and blue fringe along the edges of an object.…This happens a lot in DSLRs.…

And especially with lower quality optics like that.…it happens quite a bit.…So what we're going to do is talk about how to add this to your flares,…so that you can composite better, or…actually add more realism, too, if you wanted.…So I'm going to go ahead and click Options to…open up the optical flares options, and we'll Clear All.…To start from scratch. I'm going to…go ahead and add a glow and a streak and…we'll add also a shimmer and we'll also add an iris.…Now, the only way to get to cr…chromatic aberration is by going to Global Parameters.…
