Yes. Barrel distortion makes straight lines bow outward toward the frame edges; pincushion distortion is the opposite, with lines bending inward. Barrel distortion is commonly associated with wide-angle settings, while pincushion distortion often appears at the telephoto end of some zoom lenses. A single zoom can show both depending on focal length—for example, some lenses show barrel distortion wide and pincushion distortion when zoomed in.

Correction is typically done by remapping the image geometry using a lens distortion model, so pixels are shifted to straighten lines. Software such as PTLens and Hugin applies this correction after demosaicing the Bayer data rather than directly in the raw Bayer mosaic. In general, the process is a geometric transform based on known lens characteristics, followed by interpolation to create the corrected image.
