WebMar 16, 2024 · Photographic distortion can be divided into two categories: perspective distortion and optical (lens) distortion. Any deformation that occurs in the images created by a camera lens is lens distortion. In general, lens distortion can be defined as when straight lines in photographs appear bent or curved. WebSep 7, 2024 · What Is Lens Distortion? We say a photo is "distorted" when the lines and shapes look misshaped. This happens due to issues in your lens or because of how the lens is designed. A lens is made of many optical elements that refract and bend the light rays. Sometimes, the geometrics of a lens can cause distortion in the image.

WebOct 5, 2024 · Distortion is produced by the lens, not the sensor. So the distortion correction you describe is also referred to as lens correction. There are different distortion models (equations). The parameters depend on the specific distortion models used. Different cameras and software may use different distortion models.
