Indawo enkulu eqondiwe kanye nembobo enkului-fisheye lensisho ilensi ye-fisheye enosayizi wenzwa omkhulu (njengohlaka olugcwele) kanye nenani elikhulu lokuvula (elifana no-f/2.8 noma ngaphezulu). Ine-engeli yokubuka enkulu kakhulu kanye nenkundla yokubuka ebanzi, imisebenzi enamandla nomthelela obonakalayo oqinile, futhi ifanele izigcawu ezihlukahlukene zokudubula, ikakhulukazi ezindaweni ezinokukhanya okuphansi noma lapho kudingeka i-engeli yokubuka ebanzi, njengokuthwebula izithombe zesigcawu sasebusuku. , izithombe zezakhiwo, njll.
Izici zamalensi wamehlo ezinhlanzi anendawo enkulu eqondiwe kanye nendawo enkulu yokuvula
Indawo enkulu okuqondiwe kuyo kanye nelensi enkulu yokuvula amehlo isiphenduke ithuluzi elithakazelisayo labathwebuli bezithombe namaciko ukuze bayidale ngemiphumela yayo yokubuka eyingqayizivele kanye nenkundla yokubuka ye-ultra-wide-angle. Izici zayo zivelele:
I-engeli yokubuka ebanzi kakhulu
I-engeli yokubuka yelensi ye-fisheye ivamise ukuba nkulu kakhulu kunaleyo yelensi evamile. I-engeli yayo yokubuka ingafinyelela ku-180 degrees noma ngisho nangaphezulu, elungele ukuthwebula indawo enkulu nezikhala.
Indawo ekhanyayo
I-lens enkulu ye-fisheye lens inembobo enkulu, evumela ukukhanya okwengeziwe ukuthi kungene inzwa futhi izuze imiphumela engcono yokucabanga ngisho nasezindaweni ezinokukhanya okuphansi.
I-lens enkulu yokuvula i-fisheye
Umthelela obonakalayo onamandla
Izithombe ezithathwe ngui-fisheye lensabe nomthelela obonakalayo oqinile kanye nemiphumela yobuhle eyingqayizivele. Lesi sisho esiyingqayizivele esibonakalayo sithandwa kakhulu phakathi kwabaculi, abaklami nabathwebuli bezithombe.
Umphumela onamandla wokuhlanekezela
Ilensi ye-fisheye ikhiqiza umphumela okhethekile wokugoba wendawo, futhi lo mphumela wokuhlanekezela unikeza izithombe ezithwetshuliwe umphumela okhethekile wokubuka. Kodwa-ke, akuwona wonke umuntu othanda lo mphumela, ngakho-ke izimo lapho ungasetshenziswa khona zilinganiselwe.
Ukujula kwenkambu
Ilensi ye-fisheye inokujula kwenkundla, okusho ukuthi izigcawu eziningi zingahlala zibonakala ngokucacile ngaphansi kwelensi ye-fisheye, futhi ngeke zibonakale zifiphele ngisho noma ziseduze kakhulu nelensi.
Usayizi ohlangene nophathekayo
Amalensi e-Fisheye ngokuvamile ahlangene futhi ayaphatheka, futhi angenye yamalensi abalulekile emaphaketheni abathandi bezithombe abaningi nabathwebuli bezithombe abangochwepheshe.
Indlela yokuthwebula yelensi ye-fisheye enendawo enkulu eqondiwe kanye nendawo enkulu yokuvula
Njengoba indawo enkulu eqondiwe kanye nembobo enkului-fisheye lensinemiphumela ekhethekile ye-engeli ebanzi kanye nezici zokuthwebula izithombe, abathwebuli bezithombe badinga ukukhetha nokulawula okunengqondo ngokusekelwe kuzigcawu ezithile zokudubula ukuze bathole imiphumela emihle kakhulu yokuthwebula izithombe. Uma uthwebula ngendawo enkulu eqondiwe kanye nelensi enkulu yokuvula amehlo, ungacabangela lezi zindlela ezivamile zokuthatha izithombe:
Len ukulungiswa
Imvelo ye-engeli ebanzi ye-fisheye lens ingabangela ukuhlanekezela okukhulu, ikakhulukazi eduze nemiphetho yohlaka. Ngokusebenzisa isofthiwe yokucubungula izithombe noma amathuluzi okulungisa amalensi, izithombe ze-fisheye zingalungiswa ukuze kwenziwe imigqa eqondile esithombeni iqonde futhi kuthuthukiswe ikhwalithi yesithombe iyonke.
Izibonelo zokudutshulwa kwelensi ye-fisheye enkulu yokuvula
Isithombe sendingilizi esibhaliwe
Uhla lokuthwebula lwelensi ye-fisheye ludlula indawo engunxande yenzwa, ngakho-ke kuzokwenziwa imiphetho emnyama ngesikhathi sokuthwebula. Ngokusika indawo yesithombe esebenzayo kunzwa ibe yindingilizi ebhaliwe, ungasusa imiphetho emnyama futhi uguqule isithombe se-fisheye sibe isithombe esiyindilinga esivamile.
Ukuthungwa kwe-panoramic
I-Fisheye lensingathwebula insimu ebanzi yokubuka ngenxa yezimpawu zazo ezibanzi. Kuhlanganiswe nobuchwepheshe bokuthunga be-panoramic, izithombe eziningi ezithathwe ngamalensi e-fisheye zingahlanganiswa ukuze kutholwe isithombe esikhulu se-panoramic. Le ndlela ivame ukusetshenziswa ezigcawini ezifana nezithombe zezwe kanye nezindawo zedolobha.
Cizicelo reative
Ngenxa yemiphumela ekhethekile yelensi ye-fisheye, imiphumela ebonakalayo eyingqayizivele ingadalwa ezithombeni. Isibonelo, izici zokuhlanekezela zelensi ye-fisheye zingasetshenziswa ukuze kwandiswe izinto ezifundwayo ezisebangeni eliseduze nokudala imiphumela ekhethekile yokubuka lapho ukujula kwenkundla kukukhulu, okungasetshenziswa kwezinye izigcawu ezidinga ubuhlakani.
Ukusetshenziswa kwelensi ye-fisheye enendawo enkulu eqondiwe kanye nendawo enkulu yokuvula
Indawo enkulu okuqondiwe kuyo kanye nelensi enkulu yeso lezinhlanzi, ngenxa yokuthi ine-engeli yokubuka ebanzi kakhulu, ingathwebula indawo ebanzi futhi yakhe umphumela wokubuka oyingqayizivele. Isetshenziswa kabanzi kweminye imikhakha yobungcweti bokuthwebula izithombe kanye nezinkambu zokuthwebula izithombe.
Eizithombe zezemidlalo ze-xtreme
Emidlalweni eyeqisayo efana nokushushuluza, i-skateboarding, nokuhamba ngebhayisikili, amalensi e-fisheye anganikeza umkhakha wokubuka obanzi kakhulu amanye amalensi angeke akwazi ukuwufinyelela, okusinika umbono omusha nokuqonda ngale midlalo.
Ukukhangisa Kwezithombe Nezithombe Zobuciko
I-lens enkulu ye-fisheye lens inganikeza imiphumela ekhethekile yokubuka futhi ivamise ukusetshenziswa ekukhangiseni nasekuthwebuleni izithombe zobuciko ukuze kushiye umbono ojulile ngemibono emangalisayo.
Isithombe se-Architectural
Uma kuqhathaniswa namanye amalensi, ilensi ye-fisheye ingathola inkambu yokubuka ebanzi, futhi ingadubula izakhiwo eziphakeme kakhulu, izindawo zedolobha, njll. ngokwemibono engakaze ibonwe.
Ukusetshenziswa kwe-lens enkulu yokuvula i-fisheye
Ukubuka Kwezinkanyezi Nezithombe
Ii-fisheye lensindawo enkulu okuhloswe ngayo ingathwebula indawo yesibhakabhaka enkudlwana, okuyinzuzo enkulu yokuhlola izinkanyezi. Isibonelo, ingasetshenziselwa ukuthwebula izithombe zezinkanyezi, okuhlanganisa isibhakabhaka esinezinkanyezi, i-Milky Way, i-aurora, ukusitheka kwelanga, ukusitheka kwenyanga nezinye izigcawu, ezingabonakala ngokucacile.
Izithombe ze-Panoramic ne-VR
Ngenxa yokuthi inikeza indawo enkulu yokubuka, ilensi ye-fisheye isiphenduke inketho ekahle yokuthwebula izithombe zepanoramic engu-360-degree, futhi ihlinzeka ngemibono engcono yokuklama nesakhiwo sabadali bokuqukethwe bezithombe ze-virtual reality (VR).
