A mandala a maso a nsombandi lenzi yopingasa kwambiri, yomwe imadziwikanso kuti lenzi ya panoramic. Kawirikawiri amaganiziridwa kuti lenzi yokhala ndi kutalika kwa 16mm kapena kutalika kwafupi ndi lenzi ya fisheye, koma mu uinjiniya, lenzi yokhala ndi ngodya yowonera yoposa madigiri 140 imatchedwa lenzi ya fisheye. M'machitidwe, palinso magalasi okhala ndi ngodya zowonera zomwe zimaposa kapena kufika madigiri 270. Lenzi ya fisheye ndi gulu la kuwala lotsutsana ndi telephoto lomwe lili ndi kupotoza kwakukulu kwa mbiya. Lenzi yakutsogolo ya lenzi iyi imaonekera kutsogolo, ndipo mawonekedwe ake ndi ofanana ndi diso la nsomba, motero amatchedwa "lenzi ya fisheye", ndipo mawonekedwe ake ndi ofanana ndi a nsomba yomwe ikuwona zinthu pamwamba pa madzi.

Lenzi ya maso a nsomba

Lenzi ya fisheye imadalira kuyambitsa kupotoza kwakukulu kwa mbiya mwadala kuti ipeze ngodya yayikulu yowonera. Chifukwa chake, kupatula chinthu chomwe chili pakati pa chithunzicho, ziwalo zina zomwe ziyenera kukhala mizere yowongoka zimakhala ndi kupotoza kwina, zomwe zimapangitsa kuti pakhale zoletsa zambiri pakugwiritsa ntchito kwake. Mwachitsanzo, pankhani yachitetezo, lenzi ya fisheye imatha kusintha ma lenzi ambiri wamba kuti iwunikire patali. Popeza ngodya yowonera imatha kufika 180º kapena kuposerapo, palibe ngodya yoyipa yowunikira. Komabe, chifukwa cha kupotoza kwa chithunzicho, chinthucho chimakhala chovuta kuzindikirika ndi diso la munthu, zomwe zimachepetsa kwambiri luso lowonera; Chitsanzo china ndi pankhani ya robotics, ma robot odziyimira pawokha amafunika kusonkhanitsa zambiri za zithunzi za malo ozungulira ndikuzizindikira kuti achitepo kanthu koyenera.

Ngatimandala a maso a nsombaNgati ikugwiritsidwa ntchito, mphamvu yosonkhanitsa zithunzi imatha kuwonjezeka ndi nthawi 2-4, koma kusinthaku kumapangitsa kuti mapulogalamu azivuta kuzindikira. Ndiye tingazindikire bwanji chithunzicho kuchokera ku lenzi ya fisheye? Pali njira yodziwira malo a zinthu zomwe zili pachithunzichi. Koma zimakhala zovuta kuzindikira zithunzi zovuta chifukwa cha zovuta za pulogalamuyo. Chifukwa chake, njira yodziwika bwino tsopano ndikuchotsa kusokonekera kwa chithunzicho kudzera mu kusintha kosiyanasiyana, kuti tipeze chithunzi chabwinobwino kenako ndikuchizindikira.

Zithunzi za Fisheye sizinakonzedwe ndi kukonzedwa

Ubale pakati pa bwalo la chithunzi ndi sensa ndi motere:

Ubale pakati pa bwalo la chithunzi ndi sensa

Poyamba,magalasi a maso a nsombaAnkagwiritsidwa ntchito pojambula zithunzi chifukwa cha kukongola kwawo kwapadera chifukwa cha kusokonekera kwa migolo yomwe amapanga panthawi yojambula zithunzi. M'zaka zaposachedwa, kugwiritsa ntchito lenzi ya fisheye kwakhala kukugwiritsidwa ntchito kwambiri m'munda wa kujambula zithunzi za wide-angle, zankhondo, zowunikira, zoyeserera panoramic, zowonetsera zozungulira ndi zina zotero. Poyerekeza ndi magalasi ena, lenzi ya fisheye ili ndi ubwino wa kulemera kopepuka komanso kukula kochepa.
