Iilensi zekona ebanzizibonelela ngebala elibanzi lombono, ezivumela ukuba zibambe ububanzi bendawo. Nangona kunjalo, ngenxa yeemeko zokukhanya ezinqongopheleyo ezifumaneka kwimifanekiso yasebusuku, zibeka iimfuno ezingqongqo kwiindawo zokubonisa kwaye zifuna ukusetyenziswa kwezakhono ezithile zobugcisa.
1.Useto lwe-Aperture
Ukuseta i-aperture kufuna ukulinganisela ubunzulu bentsimi nomgangatho womfanekiso; ukuze kufezekiswe ubunzulu obukhulu bentsimi kunye nesiphumo se-"starburst" esivela kwimithombo yokukhanya, kuyacetyiswa ukusebenzisa i-aperture ngaphakathi koluhlu lwe-f/8 ukuya kwi-f/16. Uninzi lweelensi zibonelela ngesisombululo sazo esifanelekileyo kunye nobukhali malunga ne-f/8 ukuya kwi-f/11; xa i-aperture imisiwe ukuya kwi-f/11 okanye encinci (umz., f/16), imithombo yokukhanya ekwindawo yomboniso—njengezibane zasesitalatweni—iya kudlula kwi-diffraction ukuze ivelise iziphumo ezintle ze-starburst.
Umzekelo, xa uthatha imifanekiso yesixeko eqhelekileyo ebusuku, ukubeka umngxuma kwi-f/8–f/11 kuqinisekisa ukuba umngxuma ongaphambili kunye nomva uhlala ubukhali; nangona kunjalo, kwimiboniso ekhethekileyo efana ne-astrophotography okanye iindlela zeenkwenkwezi, kufuneka umiselo olubanzi lomngxuma—ingakumbi umngxuma omkhulu phakathi kwe-f/2.8 kunye ne-f/4—ukuze kubanjwe ukukhanya okwaneleyo.
2.Useto lwe-Shutter
Isantya se-shutter simisela ubude bokukhanya kunye nokubonakaliswa kweziphumo zentshukumo; ngokwesiqhelo, kufuneka ihlengahlengiswe ngokweemeko zokukhanya okungqongileyo, kunye nezicwangciso eziqhelekileyo eziqala kwimizuzwana emi-2 ukuya kweli-10. Okukhona i-shutter ihlala ivuliwe ixesha elide, kokukhona ukukhanya okungaphezulu kungena kwikhamera, nto leyo ebangela umfanekiso oqaqambileyo ngokubanzi; ngenxa yoko, ukwandisa ubude be-shutter kunokunceda ukuphucula iinkcukacha kwizithunzi.
Umzekelo, ukuze ubambe iindlela zeendlela ezihambayo okanye imiqolo yokukhanya, ungandisa isantya sokuvala siye phakathi kwemizuzwana eli-10 ukuya kwengama-30. Ngokwahlukileyo koko, ukuba ukukhanya okukufutshane kukhazimle (njengakwindawo exakekileyo yezorhwebo), isantya sokuvala singancitshiswa sibe yimizuzwana eli-1 ukuya kweyesi-2 ukuthintela ukuchatshazelwa kakhulu kwiindawo eziphambili.
Kubalulekile ukuqaphela ukuba kufuneka kusetyenziswe i-tripod ngexesha lokudubula.iilensi zekona ebanziinika umbono obanzi, nokuba ukushukuma okuncinci kwekhamera ngexesha lokuvezwa ixesha elide kusenokwenza umfanekiso ube mfiliba, nto leyo eyenza ukufota ngesandla kungabi luncedo.

3.Useto lobuntununtunu be-ISO
I-ISO yeyona nto iphambili ebangela ingxolo yomfanekiso; nangona useto lwe-ISO ephezulu lunokunyusa ukukhanya, lukwanyusa ingxolo. Ukuba ukubonakaliswa okufanelekileyo kugcinwa, kufuneka uhlale ubeka phambili ukusebenzisa i-ISO yekhamera (ngesiqhelo i-ISO 100) ukuze ufumane imifanekiso ecocekileyo nengenangxolo ingako.
Cinga kuphela ngokuphakamisa i-ISO—umzekelo, iye kwi-800 okanye kwi-1600—xa zombini i-aperture kunye nesantya se-shutter sele zityhalelwe kwimida yazo, kodwa umfanekiso uhlala umnyama kakhulu.
4.Useto lokugxila
Kwiimeko eziphantsi kokukhanya, i-autofocus isenokungachaneki ngokupheleleyo. Ke ngoko, xa ufota ebusuku, kuyacetyiswa ukuba ubeke phambili ukugxila ngesandla kwaye ubeke indawo yokugxila kwi-infinity (∞) okanye ugxile ngqo kwinkwenkwezi ekhanyayo.
Ungasebenzisa umsebenzi we-Live View ukuze ukhulise umfanekiso kwaye uqinisekise ukuchaneka kokugxila, ngaloo ndlela uqinisekise ukuba umphambili kunye nomva zihlala zibukhali. Ukuba ikhamera yakho ixhasa ukukhulisa kwesikrini ukuze kugxilwe, ungasondeza umfanekiso ukuqinisekisa ukuba ukugxila kuchanekile.
I-ISO kunye noseto lokugxila kwiilensi ezibanzi nazo zibalulekile
5.Iisetingi zokuhlawula umngcipheko wokuvezwa
Xa kufotwa imifanekiso yesixeko ebusuku, imithombo yokukhanya okunamandla—njengezibane zasezitalatweni okanye iimpawu ze-neon—ihlala ikhona. Phantsi kwezi meko, inkqubo yokulinganisa ikhamera ithanda ukuvezwa okumnyama ngokubanzi, okunokubangela ukuba iindawo ezikhanyayo zomfanekiso zibe nombala ogqithisileyo.
Ukujongana nale meko, kuyimfuneko ukusebenzisa imbuyekezo efanelekileyo yokuchatshazelwa—ngokwesiqhelo ngokunciphisa ukuchatshazelwa nge-0.3 ukuya kwi-0.7 EV—ukuthintela ukulahleka kweenkcukacha kwiindawo eziphambili; kungenjalo, uhlengahlengiso lokuchatshazelwa lunokwenziwa ngexesha lokucubungula emva koku.
6.Useto lwefomathi yokudubula
Xa kufotwa iziqendu zasebusuku ngeilensi yekona ebanzi, kuyacetyiswa ukusebenzisa ifomathi yeRAW; oku kugcina uluhlu oluphezulu lwe-dynamic, okwenza kube lula ukubuyiselwa kweenkcukacha ze-highlight kunye ne-shadow, kunye nokulungiswa kwe-white balance, ngexesha lokucubungula emva.
Xa uthatha imifanekiso yasebusuku ngelensi ebanzi, qwalasela kakhulu useto lokuhlawula ukuvezwa
7.Useto lwemo yokulinganisa
Phantsi kweemeko zokukhanya okufanayo, imo yokulinganisa uvavanyo ingasetyenziselwa ukulinganisa ukuvezwa ngokubanzi kwendawo. Le mo iqwalasela zombini iindawo ezikhanyayo nezimnyama zesakhelo ukuze inike ixabiso lokuvezwa elilinganayo.
Ukuba indawo ibonisa umahluko omkhulu—njengaxa ufota uyilo lwezakhiwo apho iindawo ezikhanyisiweyo zahluke kakhulu kwizithunzi ezinzulu—ungakhetha i-Center-weighted Average okanye i-Spot Metering. Ngokuqondisa i-metering kwiindawo ezikhanyayo okanye ezimnyama zefreyimu, unokuqinisekisa ukuba ukuvezwa kwezo ndawo zithile kuchanekile.
Ngaphezu koko, ukususela okoiilensi zekona ebanziUkubamba inani elikhulu lezinto zesiganeko, kufuneka kuqwalaselwe ngokukodwa ulawulo lokuvezwa kwimiphetho yesakhelo. Ngaphaya kwezicwangciso zokuvezwa, ukuba nobuchule bokudubula—njengokukhetha ukudubula ngexesha “legolide”—kunokuphucula iinkcukacha ezibonakalayo kwaye kuphucule kakhulu umgangatho womfanekiso wokugqibela.
Ngamafutshane, ngokulungelelanisa ngokufanelekileyo iiparameter ezifana nokuvula, isantya se-shutter, kunye novakalelo lwe-ISO—kunye neendlela ezithile zokudubula—umntu unokulawula ngempumelelo ukuvezwa aze athathe iifoto zasebusuku ezikumgangatho ophezulu.
Iingcinga Zokugqibela:
