A fisheye lens is quite specialised and not generally used for every day photography due to its highly distorted imagery. However it’s extremely wide angle of view is very useful in some applications.
why is it called a fisheye lens?
The term fisheye was coined in 1906 by American physicist and inventor Robert W. Wood based on how a fish would see an ultra wide hemispherical view from beneath the water.
How was a Fisheye lens originally used?
Their first practical use was in the 1920s for use in meteorology. Formerly known as “whole sky lenses,” they were originally used to study cloud formations because of their extreme wide angle of view. Mass produced fisheye lenses for photography first appeared in the early 1960s.
How is a fisheye lens used Today?
These lens have high distortion, but there are a few ways to use a fisheye lens effectively. Favorites are landscape and travel photography. With an angle of view between 100 and 180 degrees, it will allow you to capture panoramic photos of landscapes, architectural buildings, and urban settings.
Fisheye lenses are also great for getting shots that you’d otherwise miss. Let’s say you’re shooting a city from the perspective of a rooftop. Using any other lens, it would be almost impossible to fit a whole city in your frame, but a fisheye len will distort the scene so it works. Plus, the distorted lines will add drama and meaning to your photo. The key is to use the curves to attract the viewer and draw their attention to a specific part of your photo.
The use of fisheye lenses in science
Fisheye lenses are also used in highly specialized scientific photography areas to study plant canopy geometry, to calculate near-ground solar radiation and for recording aurora and meteors. A common use is peephole door viewers to give the user a wide field of view.
Lens ya jicho la samaki ni maalumu sana na kwa ujumla haitumiki kwa upigaji picha wa kila siku kwa sababu ya picha zake zilizopotoka sana. Hata hivyo ni pembe kubwa sana ya mtazamo ni muhimu sana katika baadhi ya maombi. Kwa nini lensi ya macho ya samaki? "Jina ""Fish Eye"" lilitokana na nadharia ya Robert Wood, mwanasayansi wa Marekani, ambaye alianzisha nadharia ya ""Fish Eye"" mwaka 1906 kwa sababu ya jinsi samaki wanavyoweza kuona sehemu ya dunia iliyo chini ya maji." Lens ya Fisheye ilitumiwaje mwanzoni? Matumizi ya kwanza ya vifaa hivyo yalikuwa katika miaka ya 1920 kwa ajili ya matumizi katika hali ya hewa. Zilizojulikana zamani kuwa "lens za anga nzima", awali zilitumiwa kuchunguza miundo ya mawingu kwa sababu ya pembe yao pana sana ya kuona. Lens za macho ya samaki zilizotengenezwa kwa wingi kwa ajili ya upigaji picha zilionekana kwa mara ya kwanza mwanzoni mwa miaka ya 1960. Lens ya jicho la samaki hutumiwaje leo? Lens hizi zina upotoshaji mkubwa, lakini kuna njia chache za kutumia lens ya jicho la samaki kwa ufanisi. Anapenda sana kupiga picha za mandhari na za kusafiri. Kwa pembe ya kuona kati ya digrii 100 na 180, itawawezesha kupiga picha za mandhari, majengo ya usanifu, na mazingira ya mijini. Lens za Fisheye pia ni nzuri kwa kupata picha ambazo vinginevyo ungepoteza. Hebu tuseme wewe ni risasi mji kutoka mtazamo wa paa. Kwa kutumia lensi nyingine yoyote, itakuwa karibu haiwezekani kuweka mji mzima katika sura yako, lakini lensi ya jicho la samaki itapotosha eneo hilo ili iweze kufanya kazi. Kwa kuongezea, mistari iliyopotoka itaongeza drama na maana kwa picha yako. Njia bora ni kutumia curves ili kuvutia watazamaji na kuvutia sehemu maalum ya picha yako. Lens za macho ya samaki hutumiwa katika maeneo ya upigaji picha wa kisayansi wa kitaalamu sana kusoma jiometri ya canopy ya mmea, kuhesabu mionzi ya jua karibu na ardhi na kurekodi aurora na meteor. Matumizi ya kawaida ni peephole mlango viewers kutoa mtumiaji uwanja mpana wa mtazamo.
