barrel distortion in photography

What is distortion in photography?
Image distortion is when the straight lines of an image appear to be deformed or curved unnaturally, creating different distortion types, including barrel, pincushion, and waveform.
Distortion is often the result of the lens's geometrics and can significantly disrupt the image's quality.
Barrel distortion is a common issue faced by photographers, especially when using wide-angle lenses.
It is a form of lens distortion that causes straight lines near the edges of an image to appear curved or bent outwards.

How do you correct barrel distortion in image?

Lens barrel distortion can be corrected in post-processing using software tools such as Adobe Lightroom, Photoshop, or other image editing software.
Most image editing software includes a lens correction tool that can automatically correct for distortion based on the lens profile._{7 sept. 2023}

What is barrel distortion?

Barrel lens distortion is an effect associated with wide-angle lenses and, in particular, zoom wide-angles.
This effect causes the image to spherize, which means that the edges of the photo look curved and bowed to the human eye._{4 oct. 2021}

Barrel distortion describes a type of distortion wherein lines that are straight in real life appear to curve inwards (like the walls of a barrel). A good way to check for barrel distortion is to look for parallel lines in the area you are shooting and see if the lines appear parallel in your image.
