barrel distortion correction

Does built-in camera lens correction correct barrel distortion?
Built-in camera lens correction is generally optimized for correcting mild to moderate levels of barrel distortion. However, if the distortion in an image is particularly severe or complex, the correction algorithms may struggle to provide satisfactory results.
How to fix barrel distortion?
Barrel distortion can be corrected very easily in modern image editing programs such as Adobe Photoshop, which contains a lens distortion correction filter. Many free photo editing programs also include solutions to the problem.
What is barrel distortion in photography?
In photography, distortion is particularly associated with zoom lenses, particularly large-range zooms, but may also be found in prime lenses, and depends on focal distance – for example, the Canon EF 50mm f/ 1.4 exhibits barrel distortion at extremely short focal distances.
What is barrel distortion vs vignetting?
Barrel distortion is a lens defect that causes straight lines to bow out toward the edges of the image. Pincushion distortion is the opposite effect, where straight lines bend inward. Vignetting is a defect that darkens the corners of an image due to light falloff around the perimeter of the lens.
