1.Yintoni ilensi enekona ebanzi?

A ilensi enekona ebanziyilensi enobude obufutshane befocal. Iimpawu zayo eziphambili yi-wide viewing angle kunye ne-vision ecacileyo.

Iilensi ezibanzi zisetyenziswa kakhulu kwimifanekiso yelizwe, ubugcisa bokwakha, ubugcisa bokufota ngaphakathi, kwaye xa ukudubula kufuneka kuthathwe uluhlu olubanzi lwemiboniso.

2.Yintoni enokunceda ilensi enekona ebanzi?

Iilensi ezineekona ezibanzi ikakhulu zisetyenziswa ngolu hlobo lulandelayo:

Gxininisa isiphumo sokusondela

Ngenxa yokuba ilensi ebanzi inobunzulu obukhulu bentsimi, inokufezekisa isiphumo esiqinileyo sokusondela. Ukusebenzisa ilensi ebanzi ukufota kunokwenza izinto zangaphambili zicace njengezinto ezikude, kwandise izinto zangaphambili, kwaye kuvelise ubunzulu obucacileyo besiphumo sentsimi, kongeza imvakalelo yokubekwa kunye nobukhulu obuthathu kumfanekiso wonke.

Ilensi enekona ebanzi

Yandisa impembelelo yokujonga izinto ngendlela ezibonakala ngayo

Xa usebenzisailensi enekona ebanzi, kuya kubakho isiphumo esiphantse sibe sikhulu nesincinci kakhulu, esaziwa ngokuba yi "fisheye effect". Esi siphumo sokujonga singenza into efotweyo ibonakale ikufutshane nomjongi, inike abantu umbono onamandla wendawo kunye nobukhulu obuthathu. Ke ngoko, iilensi ezibanzi zihlala zisetyenziswa kwimifanekiso yezakhiwo ukugqamisa ubuhle kunye nomfutho wesakhiwo.

Thatha iziqephu ezinkulu

Ilensi ene-engile ebanzi inokubonisa i-engile ebanzi yokubukela, ivumela abafoti ukuba bathathe imifanekiso engaphezulu kwiifoto, njengeentaba ezikude, iilwandle, ii-panorama zesixeko, njl. Ingenza umfanekiso ube nobukhulu obuthathu kwaye uvuleke, kwaye ifanelekile kwiifoto zemiboniso ekufuneka iveze ingqiqo yendawo enkulu.

Izicelo ezikhethekileyo zokufota

Iilensi ezibanzi zingasetyenziselwa ukufota okukhethekileyo, njengokufota imifanekiso ekufutshane okanye iidokhumentari zabalinganiswa, nto leyo enokudala imiboniso ecacileyo neyokwenyani.

3.Umahluko phakathi kwelensi ebanzi kunyeeqhelekileyoilensi

Iilensi ezibanzi kunye neelensi eziqhelekileyo ziintlobo zeelensi eziqhelekileyo kwimifanekiso. Zahlukile kwezi zinto zilandelayo:

Imifanekiso ethathwe ngelensi ebanzi xa kuthelekiswa nemifanekiso ethathwe ngelensi eqhelekileyo

Uluhlu olunokubukeka

A ilensi enekona ebanziinombono omkhulu kwaye inokubamba ezinye izinto ezingqongileyo kunye neenkcukacha. Oku kuluncedo ekufoteni imimandla, iindawo zangaphakathi, okanye iindawo apho imvelaphi kufuneka igxininiswe khona.

Xa kuthelekiswa, intsimi yokujonga iilensi eziqhelekileyo incinci kakhulu kwaye ifanelekile ngakumbi ekufoteni iinkcukacha zasekuhlaleni, njengeefoto okanye izigcawu ekufuneka ziqaqambise umxholo.

I-engile yokufota

Ilensi ene-engile ebanzi idubula ukusuka kwi-engile ebanzi kunelensi eqhelekileyo. Ilensi ene-engile ebanzi inokubamba uluhlu olubanzi lweziqendu kwaye ifake ngokupheleleyo umfanekiso obanzi kwifreyimu. Xa kuthelekiswa, iilensi eziqhelekileyo zine-engile yokudubula encinci kwaye zifanelekile ukuthwebula iziqendu ezikude.

Pisiphumo sokubona

Ekubeni uluhlu lokudubula lwelensi ebanzi lukhulu, izinto ezikufutshane zibonakala zinkulu ngelixa imvelaphi ibonakala incinci. Esi siphumo sombono sibizwa ngokuba yi-"wide-angle distortion" kwaye sibangela ukuba izinto ezikufutshane zijike kwaye zibonakale zibonakala ngakumbi.

Ngokwahlukileyo koko, isiphumo sokujonga iilensi eziqhelekileyo siyinyani ngakumbi, kwaye umlinganiselo wokusondela kunye nemvelaphi usondele kwimeko yokwenyani yokujonga.

4.Umahluko phakathi kwelensi ye-wide-angle kunye nelensi ye-fisheye

Umahluko phakathi kwelensi ebanzi kunye nelensi yefisheye ikakhulu usekwe kwicandelo lokujonga kunye nesiphumo sokuphambuka:

Uluhlu olunokubukeka

A ilensi enekona ebanziidla ngokuba nebala elibanzi lokujonga kunelensi eqhelekileyo, nto leyo evumela ukuba ibambe indawo engaphezulu. I-engile yokujonga kwayo idla ngokuba phakathi kwama-degree angama-50 nama-degree angama-85 kwikhamera enesakhelo esipheleleyo esingama-35mm.

Ilensi yefisheye inombono obanzi kakhulu kwaye inokufota imifanekiso engaphezulu kwe-180 degrees, okanye imifanekiso ebanzi. Ke ngoko, i-engile yayo yokubukela inokuba nkulu kakhulu kunelensi ye-engile ebanzi, edla ngokuba yi-180 degrees kwikhamera epheleleyo.

Imifanekiso ethathwe ngelensi yefisheye

Isiphumo sokuphambuka

Iilensi ezibanzi azinazo iimpazamo ezininzi kwaye zinokubonisa ubungakanani beendawo ezibonakala ngokwenene kunye neemilo zemigca. Ziyandisa kancinci izinto ezikufutshane, kodwa isiphumo sokuphazamiseka sincinci kakhulu.

Ilensi yefisheye inesiphumo esicacileyo sokuphambuka, esibonakaliswa kukwanda okucacileyo kwezinto ezikufutshane, ngelixa izinto ezikude zincipha, nto leyo ebangela ukuba kubekho umfanekiso ogobileyo okanye ongqukuva, obonisa isiphumo esikhethekileyo sefisheye.

Injongo kunye neemeko ezifanelekileyo

Ilensi ene-engile ebanzi ifanelekile kwimifanekiso efuna umbono obanzi, njengeembonakalo zomhlaba, uyilo lwedolophu, ukudubula ngaphakathi, njl. Idla ngokusetyenziselwa ukuthwebula iindawo ezinkulu zembonakalo ngelixa igcina umbono kunye nokwenyani.

Ngokwahlukileyo koko, iilensi ze-fisheye zifanelekile ekudaleni iziphumo ezibonakalayo ezizodwa kwaye zinokuvelisa iziphumo eziphazamisayo kwiindawo ezithile, njengeendawo ezincinci zangaphakathi, iindawo zemidlalo, okanye indalo yobugcisa.
