Fish-eye Filter A fish-eye filter is a type of optical filter used in photography to mimic the visual distortion produced by a fish-eye lens. Fish-eye filters are typically attached to the front of a camera lens and feature a convex, wide-angle lens element that captures an extremely wide field of view, resulting in extreme barrel distortion and a characteristic spherical or hemispherical perspective.
Fish-eye filters are used to create exaggerated, surreal, and immersive images with unique visual effects, such as curved horizons, elongated objects, and distorted proportions. They are popular in experimental and artistic photography, as well as in specialized applications such as panoramic and 360-degree imaging. |
