"Fisheye lens"
It is basically a wide-angle optical lens that produces durable visual distortion presupposed to type a decent wide or figure image. Camera lens lenses return through terribly wide angles of reading. instead of producing footage with straight lines of perspective (rectilinear images), camera lens lenses use a special mapping (for example equisolid angle), that provides footage of a characteristic lentiform non-rectilinear look.
Fisheye camera lens was first coined in 1906 by American artificer Henry M. Robert W. Wood, however, a fish would see associate immoderate wide figure browse from to a lower place the water Their initial wise use was inside the Twenties to be utilized in meteorology, to see cloud formation giving them the name "whole-sky lenses".
The angle of reading of an optical lens is usually between 100 to hundred and eighty degrees whereas the focal lengths betting on the file format they are designed for. Factory-made camera lens lenses for photography initial appeared inside the first Sixties that area unit usually used as a particular, distorted look.
For the favoured thirty 5 mm film format, typical focal lengths of camera lens lenses area unit between eight millimetres and 10 millimetres for circular footage, and 15–16 mm for full-frame footage.
The fish-eye lenses are the mainstream choices for the photography geeks when they desire to capture wide-angle shots.
