all camera lenses exhibit degrees of distortion. most common with wide-angle lenses and lenses with large zoom ranges. Luminar 2018 has tools within the Develop module to autocorrect this distortion, Luminar now offers fast automatic corrections for lens distortion, chromatic aberrations, and removing fringes.
I created this How to video tutorial and I hope to be helpful to everyone.
