1.Iyini ilensi ene-angle ebanzi?

A ilensi ene-engeli ebanziilensi enobude obufushane bokugxila. Izici zayo eziyinhloko i-wide viewing angle kanye nomphumela osobala wombono.

Amalensi ane-engeli ebanzi asetshenziswa kabanzi ekuthwebuleni izithombe zezwe, izithombe zezakhiwo, izithombe zangaphakathi, kanye nalapho ukudubula kudinga ukuthwebula izigcawu eziningi.

2.Iyini ukusetshenziswa kwelensi ene-angle ebanzi?

Amalensi ane-engeli ebanzi asetshenziswa kakhulu ngokulandelayo:

Gcizelela umphumela wokusondelana

Ngenxa yokuthi ilensi ene-engeli ebanzi inobubanzi obukhulu bensimu, ingafinyelela umphumela oqinile wokusondelana. Ukusebenzisa ilensi ene-engeli ebanzi ukuthwebula kungenza izinto zangaphambili zicace njengezinto ezikude, kwandise izinto zangaphambili, futhi kukhiqize ukujula okusobala komphumela wensimu, kunezela umuzwa wokubekwa kwezigaba kanye nobukhulu obuthathu esithombeni sonke.

Ilensi ene-engeli ebanzi

Thuthukisa umphumela wombono

Uma usebenzisailensi ene-engeli ebanzi, kuzoba nomphumela ocishe ube mkhulu kakhulu nowomncane kakhulu, owaziwa kakhulu ngokuthi “umphumela we-fisheye”. Lo mphumela wokubona ungenza into ethathwe izithombe ibonakale iseduze nomuntu obukayo, inikeze abantu umuzwa onamandla wesikhala kanye nobukhulu obuthathu. Ngakho-ke, amalensi e-wide angle avame ukusetshenziswa ekuthwebuleni izithombe zezakhiwo ukugqamisa ubuhle kanye nomfutho wesakhiwo.

Thwebula izigcawu ezinkulu

Ilensi ene-engeli ebanzi ingaveza i-engeli ebanzi yokubuka, okuvumela abathwebuli bezithombe ukuthi bathwebule izigcawu ezengeziwe ezithombeni, njengezintaba ezikude, izilwandle, ama-panorama amadolobha, njll. Ingenza isithombe sibe nezinhlangothi ezintathu futhi sivuleke, futhi ifanelekela izigcawu zokuthwebula ezidinga ukuveza umuzwa wendawo enkulu.

Izinhlelo zokusebenza zezithombe ezikhethekile

Amalensi ane-engeli ebanzi angasetshenziswa futhi ekuthwebuleni izithombe ezikhethekile, njengokuthwebula izithombe eziseduze noma amadokhumentari abalingiswa, okungadala izigcawu ezicacile nezingokoqobo.

3.Umehluko phakathi kwelensi ene-wide angle kanye nelensi ye-okuvamileilensi

Amalensi ane-engeli ebanzi namalensi avamile ayizinhlobo zamalensi ezivamile ezithombeni. Ahlukile kulezi zici ezilandelayo:

Izithombe ezithathwe ngelensi ene-engeli ebanzi uma kuqhathaniswa nezithombe ezithathwe ngelensi evamile

Ibanga elibonakalayo

A ilensi ene-engeli ebanziinensimu enkulu yokubuka futhi ingathwebula indawo ezungezile kanye nemininingwane eminingi. Lokhu kuyasiza ekuthwebuleni izindawo, izindawo zangaphakathi, noma izigcawu lapho ingemuva lidinga ukugcizelelwa khona.

Uma kuqhathaniswa, insimu yokubuka amalensi avamile incane kakhulu futhi ifaneleka kakhulu ekuthwebuleni imininingwane yendawo, njengezithombe noma izigcawu ezidinga ukugqamisa isihloko.

I-engeli yokuqopha

Ilensi ene-engeli ebanzi idubula kusukela ekhoneni elibanzi kunelensi evamile. Ilensi ene-engeli ebanzi ingathwebula ububanzi bezigcawu futhi ifake ngokugcwele isigcawu esibanzi kufreyimu. Uma kuqhathaniswa, amalensi avamile ane-engeli yokudubula encane futhi afanelekela ukuthwebula izigcawu zebanga eliphakathi.

Pumphumela wokubuka

Njengoba ibanga lokudubula ngelensi ene-engeli ebanzi likhulu, izinto eziseduze zibonakala zikhulu kuyilapho ingemuva libonakala lincane. Lo mphumela wokubuka ubizwa ngokuthi “ukuhlanekezela kwe-engeli ebanzi” futhi ubangela izinto ezisensimini eseduze ukuba ziguquguquke futhi zibonakale zivelele kakhulu.

Ngokuphambene nalokho, umphumela wombono wamalensi avamile ungokoqobo kakhudlwana, futhi isilinganiso sokusondelana kanye nesizinda siseduze nesimo sangempela sokubuka.

4.Umehluko phakathi kwelensi ene-wide-angle kanye nelensi ye-fisheye

Umehluko phakathi kwelensi ene-wide-angle kanye nelensi ye-fisheye usekelwe kakhulu emkhakheni wokubuka kanye nomphumela wokuhlanekezela:

Ibanga elibonakalayo

A ilensi ene-engeli ebanzingokuvamile inensimu ebanzi yokubuka kunelensi evamile, okuyenza ikwazi ukuthwebula ingxenye enkulu yesigcawu. I-engeli yayo yokubuka ngokuvamile iphakathi kwama-degrees angaba ngu-50 nama-degrees angu-85 ekhamera egcwele uhlaka engu-35mm.

Ilensi ye-fisheye inensimu ebanzi kakhulu yokubuka futhi ingathwebula izigcawu ezingaphezu kwama-degrees angu-180, noma ngisho nezithombe ezi-panoramic. Ngakho-ke, i-engeli yayo yokubuka ingaba nkulu kakhulu kunelensi ene-engeli ebanzi, ngokuvamile engama-degrees angu-180 ekhamera egcwele uhlaka.

Izithombe ezithathwe ngelensi ye-fisheye

Umphumela wokuhlanekezela

Amalensi ane-engeli ebanzi akhiqiza ukuphambuka okuncane futhi angaveza izilinganiso zesimo ezingokoqobo kanye nokuma kwemigqa. Anweba kancane izinto eziseduze, kodwa umphumela wokuphambuka uwonke mncane kakhulu.

Ilensi ye-fisheye inomphumela wokuhlanekezela osobala, obonakala ngokwanda okusobala kwezinto eziseduze, kuyilapho izinto ezikude zincipha, okuholela esigcawini esigobile noma esiyindilinga, okubonisa umphumela oyingqayizivele we-fisheye.

Inhloso kanye nezimo ezisebenzayo

Ilensi ene-engeli ebanzi ifanelekela izigcawu zokudubula ezidinga insimu ebanzi yokubukwa, njengezindawo, izakhiwo zasemadolobheni, ukudubula ngaphakathi, njll. Ivame ukusetshenziselwa ukuthwebula izindawo ezinkulu zezindawo ngenkathi igcina umuzwa wombono kanye nokuba ngokoqobo.

Ngokuphambene nalokho, amalensi e-fisheye afaneleka ukudala imiphumela ebonakalayo ehlukile futhi angakhiqiza imiphumela ephazamisayo ezigcawini ezithile, njengezindawo ezincane zangaphakathi, izindawo zemidlalo, noma indalo yobuciko.
