Lightroom Classic includes numerous lens profiles, which can be used to correct common lens aberrations such as barrel and pincushion geometric distortion ("barrel" distortion causes straight lines to appear to bow outward, "pincushion" distortion causes straight lines to appear to bend inward). Most lens profiles also correct for vignetting (where the corners of an image appear darker than the rest of an image). In addition, Lightroom’s ability to remove chromatic aberration corrects for misaligned pixels in an image (also caused by lens distortion).
