- Barrel distortion: is an occurrence in wide angle lenses like the ones found in action cameras where images appear to bulge outwards from the center and straight lines, at the frame’s edges, curve inward resembling a barrel effect.
- Pincushion distortion: is an occurrence when using telephoto lenses where straight lines appear to bend outward from a central point, like a pincushion’s shape.
