What is radial lens distortion?
Radial lens distortion is the symmetric distortion caused by the lens due to imperfections in curvature when the lens was ground. In most cases, the errors introduced by radial lens distortion (around 1 to 2 um) are much smaller than the scanning resolution of the image (around 25um).
What is lens distortion removal?
What Is Lens Distortion Correction? A lens will always create the same type of lens distortions. Using software can often reverse that effect. Lens correction in Lightroom and Photoshop applies an algorithm based on the specific lens model. It corrects the optical distortions created by the optics of that lens.
How does distortion correction work?
As it is mentioned in the name of the feature itself 'Distortion Correction', accordingly this feature allows the camera to digitally convert and correct the captured visually deformed image, into its original and accurate shape, automatically without any of your efforts when the feature is turned ON to operate.
