pincushionové

Pincushionové, also known as pincushion distortion, is a type of optical distortion that occurs when a lens or camera system is unable to capture a flat, undistorted image. This distortion is characterized by the appearance of the image being stretched or compressed, often resembling the shape of a pincushion. It is typically more pronounced at the edges of the image, with the center remaining relatively undistorted.

Pincushion distortion can be caused by several factors, including the design of the lens, the alignment of the lens elements, and the curvature of the image sensor or film. It can also result from the use of wide-angle lenses, which are more susceptible to this type of distortion due to their wider field of view.

To correct pincushion distortion, photographers and videographers may use software tools to adjust the image, or they may use lenses that are specifically designed to minimize this type of distortion. In some cases, the distortion may be corrected during the post-processing stage of image editing.

Pincushion distortion is a common issue in photography and videography, and understanding its causes and effects can help professionals and enthusiasts to produce higher-quality images. By being aware of this type of distortion and taking steps to minimize it, photographers and videographers can ensure that their images are as accurate and true-to-life as possible.
