I really hope DA I has an option to turn chromatic Aberration off as i hope im not the only one who gets a raging headache due to it. Please

Chromatic aberration is a cheap and easy way to tie your visuals up with a bow. Just like lens flares and blooms before it, you use it to unify your image by simulating the frustrating side effects of using real-world lenses. There's a certain visual consistency you get when it looks like you took a picture of your image with a crappy camera.

 

Thankfully, I believe we've toned it down a great deal.

 

Side story: ten years ago, in art school, we were all excited about chromatic aberration and I was simulating it by nudging my color channels around by a few pixels. I sent one such image to a local print shop, and when I came to pick it up the owner looked haggard and defeated. He said "I'm so sorry... I've been here all night, there's something wrong with my [tens of thousands of dollars] printer. I've tried everything, but the colors on your poster are still off." I apologized deeply, and he almost fainted from relief when I admitted that the misaligned colors were intentional. I haven't used the technique in an image since.
