Own an Olloclip? Sure you do — you’re serious about having a beautiful Instagram feed, right?
An Olloclip is great for getting beautiful macro shots, but its lens distortion means that you have to carefully crop your photo to avoid it showing. Happily, the great folks at Olloclip have released a companion app which corrects some of this distortion. It doesn’t correct the fringing or chromatic aberration, but it’s quite good for basic barrel distortion issues, and it’s free.
