Amalensi e-engeli ebanziinikeza insimu enkulu yombono, ebavumela ukuthi bathwebule ububanzi bendawo yesehlakalo. Kodwa-ke, ngenxa yezimo zokukhanya ezilinganiselwe ezitholakala ekuthwetshulweni kwezithombe zasebusuku, babeka izidingo eziqinile kuzilungiselelo zokuvezwa futhi bafuna ukusetshenziswa kwamakhono athile obuchwepheshe.
1.Izilungiselelo ze-Aperture
Ukusetha i-aperture kudinga ukulinganisela ukujula kwensimu nekhwalithi yesithombe; ukuze kufinyelelwe ukujula okukhulu kwensimu kanye nomphumela we-"starburst" ovela emithonjeni yokukhanya, kunconywa ukusebenzisa i-aperture engaphakathi kwebanga le-f/8 kuya ku-f/16. Amalensi amaningi anikeza ukucaca kwawo okuhle kanye nokubukhali okuzungeze i-f/8 kuya ku-f/11; lapho i-aperture imiswa iye ku-f/11 noma encane (isb., f/16), imithombo yokukhanya ekhombayo ngaphakathi kwesigameko—njengezibani zasemgwaqweni—izobhekana nokuphazamiseka ukuze ikhiqize imiphumela emihle ye-starburst.
Isibonelo, lapho uthwebula izithombe zedolobha ezijwayelekile ebusuku, ukusetha imbobo ku-f/8–f/11 kuqinisekisa ukuthi kokubili ingaphambili nengemuva kuhlala kubukhali; nokho, ezigcawini ezikhethekile njenge-astrophotography noma imizila yezinkanyezi, kudingeka ukusethwa kwembobo ebanzi—ikakhulukazi imbobo enkulu phakathi kwe-f/2.8 ne-f/4—ukuze kubanjwe ukukhanya okwanele.
2.Izilungiselelo ze-Shutter
Ijubane le-shutter linquma ubude bokukhanya kanye nokubonakaliswa kwemiphumela yokunyakaza; ngokuvamile, kufanele kulungiswe ngokwezimo zokukhanya ezizungezile, ngezilungiselelo ezijwayelekile ezisukela kumasekhondi angu-2 kuya kwangu-10. Uma i-shutter ihlala ivuliwe isikhathi eside, ukukhanya okwengeziwe kungena ekhamera, okuholela esithombeni esikhanyayo; ngenxa yalokho, ukwandisa ubude be-shutter kungasiza ekuthuthukiseni imininingwane emthunzini.
Isibonelo, ukuze uthwebule imizila yethrafikhi ehambayo noma imigqa yokukhanya, ungase welule isivinini se-shutter sibe phakathi kwemizuzwana eyi-10 nengama-30. Ngokuphambene nalokho, uma ukukhanya okuzungezile kukhanya kakhulu (njengasendaweni yezentengiselwano ephithizelayo), isivinini se-shutter singafinyezwa sibe yimizuzwana eyi-1-2 ukuvimbela ukuchayeka ngokweqile ezindaweni ezivelele.
Kubalulekile ukuqaphela ukuthi i-tripod kumele isetshenziswe ngesikhathi sokuthwebula.amalensi e-wide angleinikeza umbono obanzi, ngisho nokunyakazisa ikhamera okuncane ngesikhathi sokubona isikhathi eside kusengafiphaza isithombe, okwenza ukuthwebula ngesandla kungabi wusizo.
Amalensi ane-engeli ebanzi adinga ukunakwa kwezilungiselelo ze-aperture kanye nesivinini se-shutter
3.Izilungiselelo zokuzwela ze-ISO
I-ISO iyona imbangela eyinhloko yomsindo wesithombe; yize ukusethwa kwe-ISO ephezulu kungakhuphula ukukhanya, kwandisa nomsindo. Uma nje kugcinwa ukuvezwa okufanele, kufanele uhlale ubeka phambili ukusebenzisa i-ISO yekhamera (ngokuvamile i-ISO 100) ukuze uthole izithombe ezihlanzekile nezingenamsindo kakhulu.
Cabanga kuphela ngokukhuphula i-ISO—ngokwesibonelo, ibe ngu-800 noma u-1600—lapho kokubili i-aperture kanye nesivinini se-shutter sekuvele kuphushwe kwaze kwaba semingceleni yazo, kodwa isithombe sisalokhu simnyama kakhulu.
4.Izilungiselelo zokugxila
Ezimweni eziphansi kokukhanya, i-autofocus ingase ingabi nembambo ngokuphelele. Ngakho-ke, ekuthwebuleni izithombe ebusuku, kunconywa ukuthi kubekwe phambili ukugxila ngesandla bese usetha indawo yokugxila ibe yi-infinity (∞) noma ukugxila ngqo enkanyezini ekhanya kakhulu.
Ungasebenzisa umsebenzi we-Live View ukuze ukhulise isithombe futhi uqinisekise ukunemba kokugxila, ngaleyo ndlela uqinisekise ukuthi kokubili ingaphambili nengemuva kuhlala kubukhali. Uma ikhamera yakho isekela ukukhulisa kwesikrini ukuze kugxilwe, ungasondeza isithombe ukuze uqinisekise ukuthi ukugxila kunembile.
Izilungiselelo ze-ISO kanye nokugxila kwamalensi ane-wide-angle nazo zibalulekile
5.Izilungiselelo zesinxephezelo sokudalulwa
Uma kuthwetshulwa izithombe zezindawo zasedolobheni ebusuku, imithombo yokukhanya okukhulu yendawo—njengezibani zasemgwaqweni noma izimpawu ze-neon—ivame ukuba khona. Ngaphansi kwalezi zimo, uhlelo lokulinganisa lwekhamera luvame ukuphakamisa ukuvezwa okumnyama okuphelele, okungabangela ukuthi izindawo ezikhanyayo zesithombe zibe sobala kakhulu.
Ukuze kuxazululwe lokhu, kubalulekile ukusebenzisa isinxephezelo esifanele sokuchayeka—ngokuvamile ngokunciphisa ukuchayeka ngo-0.3 kuya ku-0.7 EV—ukuvimbela ukulahleka kwemininingwane ezintweni ezivelele; ngaphandle kwalokho, ukulungiswa kokuchayeka kungenziwa ngesikhathi sokucubungula ngemuva kokucubungula.
6.Izilungiselelo zefomethi yokudubula
Uma kudutshulwa izigcawu zasebusuku ngeilensi ye-engeli ebanzi, kunconywa ukusebenzisa ifomethi ye-RAW; lokhu kulondoloza ububanzi obukhulu be-dynamic, okwenza kube lula ukubuyiselwa kwemininingwane yokugqamisa kanye neyesithunzi, kanye nokulungiswa kwebhalansi emhlophe, ngesikhathi sokucubungula ngemuva.
Uma uthwebula izigcawu zasebusuku ngelensi ebanzi, naka kakhulu izilungiselelo zokunciphisa ukuchayeka
7.Izilungiselelo zemodi yokukala
Ngaphansi kwezimo zokukhanya okufanayo, imodi ye-Evaluative Metering ingasetshenziswa ukukala ukuvezwa okuphelele kwendawo. Le modi icabangela izindawo ezikhanyayo nezimnyama zohlaka ukuze inikeze inani lokuvezwa elilinganiselwe.
Uma indawo ibonisa ukungafani okukhulu—njengalapho uthwebula izithombe zezakhiwo lapho izindawo ezikhanyisiwe zihluke kakhulu ezithunzini ezijulile—ungakhetha i-Center-weighted Average noma i-Spot Metering. Ngokuqondisa i-metering ezingxenyeni ezikhanyayo noma ezimnyama zohlaka, ungaqinisekisa ukuthi ukuvezwa kwalezo zindawo ezithile kunembile.
Ngaphezu kwalokho, kusukelaamalensi e-wide angleUma uthwebula inani elikhulu lezinto zesigcawu, ukunaka okukhethekile kumele kunikezwe ekulawuleni ukuchayeka emaphethelweni ohlaka. Ngale kwezilungiselelo zokuchayeka, ukwazi amasu athile okudubula—njengokukhetha ukudubula ngesikhathi “sehora legolide”—kungathuthukisa imininingwane ebonakalayo futhi kuthuthukise kakhulu ikhwalithi yesithombe sokugcina.
Ngamafuphi, ngokulungisa ngokufanele amapharamitha afana nokuvula, isivinini se-shutter, kanye nokuzwela kwe-ISO—kuhlanganiswe namasu athile okudubula—umuntu angalawula ngempumelelo ukuvezwa futhi athwebule izithombe zasebusuku ezisezingeni eliphezulu.
Imicabango Yokugcina:
Ngokusebenzisana nochwepheshe eChuangAn, kokubili ukuklama kanye nokukhiqiza kuphathwa onjiniyela abanekhono eliphezulu. Njengengxenye yenqubo yokuthenga, ummeleli wenkampani angachaza ngokuningiliziwe ulwazi oluthile mayelana nohlobo lwelensi ofisa ukuyithenga. Uchungechunge lwemikhiqizo yelensi kaChuangAn lusetshenziswa ezinhlobonhlobo zezicelo, kusukela ekuqapheni, ekuskeneni, kuma-drones, ezimotweni kuya emakhaya ahlakaniphile, njll. I-ChuangAn inezinhlobo ezahlukene zamalensi aqediwe, angashintshwa noma enziwe ngezifiso ngokwezidingo zakho. Xhumana nathi ngokushesha okukhulu.
