Uma kuqhathaniswa namalensi e-varifocal,amalensi okugxila agxilileinikeza ikhwalithi yesithombe ephezulu, kufaka phakathi ukulungiswa okuphezulu, ukuphambuka okuncane, kanye nokukhiqizwa kombala okungcono, okwenza kube ukukhetha okuthandwayo kwabathwebuli bezithombe abaningi abathwebula izindawo. Ezithombeni zezindawo, amalensi okugxila agxilile anobude obuhlukene bokugxila anikeza imibono ehlukene kanye nezici zesithombe, okuholela ezithombeni ezinezitayela ezihlukile.
Ngezansi, ake sibheke kabanzi izimo ezahlukene zokusetshenziswa kwamalensi okugxila angaguquki anobude obuhlukene bokugxila ezithombeni zezwe:
1.I-Ultra ububanzi i-engeliukugxila okugxilileilensi
Amalensi okugxila agxilile nge-angle ebanzi kakhulu anobude obuphakathi kuka-10mm no-24mm. Inzuzo yawo eyinhloko insimu yawo yokubuka ebanzi kakhulu, engamukela inani elikhulu lezinto zesigcawu. Angathwebula izindawo ezinkulu, izindawo eziqinile, nokuningi, ngenkathi enweba izendlalelo zendawo futhi egqamisa "ubuhle" besigcawu, okwenza afaneleke ukukhombisa izigcawu ezinkulu.
Le lensi ye-engeli ebanzi kakhulu ifanelekela ukuthwebula izindawo lapho "isibhakabhaka nomhlaba kuyinto eyodwa," njengezintaba ezimbozwe yiqhwa, izindawo ezinotshani ngaphansi kwezinkanyezi, izindawo ezisogwini, kanye nezigodi. Isithombe esisodwa singahlanganisa indawo engaphambili, indawo ephakathi, kanye nesizinda, sithuthukise umuzwa wokujula kwendawo.
Isibonelo, lapho uthwebula isithombe sentaba embozwe yiqhwa ngelensi yokugxila ebanzi engu-14mm, ungafaka amatshe, izimbali zasendle, noma umfudlana ngaphambili, ugcine utshani noma amahlathi endaweni ephakathi, bese ugxila esiqongweni esikhulu sentaba embozwe yiqhwa ngemuva. Lokhu kudala ukwakheka okunezendlalelo kusuka kude kuya phezulu, kugqamisa ubuhle obuhle bentaba.
Amalensi okugxila agxilile e-Ultra wide angle afanele ukuthwebula izigcawu ezinkulu
2.Ububanzi i-engeliukugxila okugxilileilensi
I-engeli ebanziamalensi okugxila agxilileinobude obuqondile obungaba ngu-24mm-35mm, obuseduze nombono wemvelo weso lomuntu kunamalensi e-ultra wide angle. Ahlanganisa umuzwa wendawo yelensi e-wide angle kanye nokuphambuka okuncane, okuvumela ukuthi uthwebule imininingwane emihle ezigcawini zansuku zonke futhi ufake izakhi zomuntu. Lolu hlobo lwelensi e-wide angle fixed focus lufanelekela ukuthwebula izithombe zezindawo nabantu kuzo, njengabahambi ohambweni, abelusi emasimini, noma abasubathi ogwini lolwandle.
Isibonelo, ilensi yokugxila eqondile ebanzi ingafaka imigwaqo, izihlahla, noma abahamba ngezinyawo lapho bethwebula imigqa yedolobha, igweme ukubanda kwezithombe zezakhiwo kuphela; lapho ithwebula izithombe zezindawo ezindala, ingathwebula ngasikhathi sinye ukujula kwemigwaqo kanye nemininingwane yezakhiwo ezinhlangothini zombili, ibonise isimo sezulu esijabulisayo sedolobha.
3.Okujwayelekileukugxila okugxilileilensi
Amalensi okugxila ajwayelekile anobude obuqondile obungaba ngu-50mm, obuhambisana kahle nensimu yokubuka kweso lomuntu. Lokhu kuphumela ezithombeni zemvelo nezingokoqobo ngaphandle kokuphazamiseka okukhulu kombono. Aguquguqukayo kakhulu futhi afaneleka ukuthwebula izindawo zobuntu ezinezici nezindawo, kanye nezigcawu zemvelo eziphakathi nendawo.
Lawa malensi okugxila ajwayelekile afaneleka kakhulu ekuthwebuleni izindawo ezidinga umbono "oqondile novinjelwe", noma ekuthwebuleni "ingqikithi emininingwaneni," eveza izilinganiso zendawo ezingokoqobo kakhulu.
Isibonelo, uma usebenzisa ilensi yokugxila ejwayelekile ukuthwebula amasimu elayisi, izilinganiso zezinhlanga zerayisi, izintaba zasensimini, nezindlu ezikude esithombeni ziyavumelana neqiniso, ziveza umuzwa "wobuhle obulula." Ukuthwebula izithombe zokukhanya echibini (njengezintaba ezimbozwe yiqhwa ezibonakala emanzini), amamaki amanzi emadwaleni, noma amaqabunga awile antanta emfuleni kuvumela umuntu ukuba adlulisele incazelo enkulu ngalezi zigcawu ezincane.
Izithombe ezithathwe ngelensi yokugxila egxilile ejwayelekile zingokwemvelo futhi zingokoqobo
4.Isithombe esiphakathi nendawoukugxila okugxilileilensi
Isithombe esiphakathi nendawoamalensi okugxila agxilileanobude obuqondile obungaba ngu-85mm-135mm. Uma kuqhathaniswa namalensi okugxila agxilile ane-wide-engile, acindezela isikhala, asondeze izinto ezikude neziseduze eduze. Lokhu kwenza izendlalelo ezahlukene zezinto ohlakeni, njengezintaba ezikude, amahlathi aphakathi nendawo, kanye namagquma aseduze, zibonakale zisondelene, okuholela ekujuleni okunamandla.
Nakuba la malensi okugxila aqinile e-telephoto angakwazi ukuthwebula izigcawu ezinkulu, avelele ekugqamiseni amaphethini athakazelisayo, ukuthungwa, kanye nezakhiwo ngaphakathi kwesigcawu, okwenza afanelekele ukudala izithombe ezizolile, ezingaqondakali, noma ezinhle ngokomthetho.
Isibonelo, lapho kuthwetshulwa izithombe zamasimu anezitezi, ilensi yokugxila eqondile ye-telephoto ephakathi nendawo ivumela izendlalelo eziseduze, eziphakathi, nezikude zamasimu ukuthi zihlangane ohlakeni. Amajika akhiwe yizitezi zasensimini aqala ngaphambili aye ngemuva, kuyilapho ngesikhathi esifanayo ecindezela isilinganiso sesibhakabhaka, okwenza amasimu anezitezi abe yindawo egxile ngokuphelele yesithombe futhi egqamisa ubuhle bawo "bomfanekiso womhlaba".
Lapho kuthwetshulwa isithombe sephayini yokwamukela yeNtaba iHuangshan, ilensi yokugxila eqondile ye-telephoto ephakathi nendawo ingacindezela ulwandle lwamafu ngemuva kanye neziqongo ezikude, okwenza iphayini yokwamukela ibe yindawo ebonakalayo ngokuphelele. Ngesikhathi esifanayo, ulwandle lwamafu, ngenxa yokucindezelwa, lungaveza ukuthungwa okuxinene nokukhulu, kuvimbele isithombe ukuthi singabonakali sigcwele.
Amalensi okugxila aqinile e-telephoto aphakathi nendawo kuya kwamade angathwebula izinto emazingeni ahlukene ngaphakathi kwesigcawu
5.I-Telephotoukugxila okugxilileilensi
Amalensi okugxila aqinile e-Telephoto ngokuvamile anobude obuqondile obungaphezu kuka-135mm, ngokuvamile ngaphezu kuka-200mm. Anensimu yokubuka emincane kakhulu futhi ahlinzeka ngokucindezela okukhulu kwendawo, okusondeza izinto ezikude. Aphinde abe namakhono amahle kakhulu e-bokeh, okwenza afaneleke ukuthwebula imininingwane ekude noma izindawo ezingabonakali, kanye nokwembula imininingwane namaphethini angabonakali okunzima ngeso lomuntu ukuwabona.
Lezi zithombe ze-telephotoamalensi okugxila agxililezilungele ukuthwebula izithombe zezindawo kanye nokusondelana kwezinto ezingafinyeleleki, njengezindawo zokuhlala zezilwane zasendle, izimpophoma emaweni, imininingwane yezintaba ezimbozwe yiqhwa, kanye nezakhiwo ezikude.
Isibonelo, lapho kuthwetshulwa izithombe zeqhwa lase-Antarctica, ilensi yokugxila eqondile ye-telephoto ingakhulisa ukwakheka kweqhwa eliluhlaza okwesibhakabhaka kanye nemifantu ebusweni beqhwa, okwenza iziqhwa ezikude zibonakale “ziseduze futhi ziyimfihlo,” ziveza kokubili ubukhulu kanye nobuhlakani bendawo esenyakatho.
Uma uthwebula izithombe zamahlane, usebenzisa ilensi yokugxila engaguquki engu-300mm ukuze uthwebule amagagasi esihlabathi, futhi ucindezela ingemuva, amagagasi akhiwa amagagasi aba yinto eyodwa kuphela ohlakeni, ekhombisa ubuhle bejometri yehlane.
Ngaphezu kwalokho, kunezinye izibuko ezikhethekile zokugxila eziqinile, njengezibuko zokugxila eziqinile ze-fisheye, okuthi, ngenxa ye-engeli yazo ebanzi kakhulu, zikhiqize imiphumela enamandla yokuphambuka esithombeni, okwenza zifanelekele izithombe zokudala ezifana nokubukwa kwesibhakabhaka okubanzi kanye nama-domes ezakhiwo.
Imicabango Yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
