Iilensi zokugxila ezizinzileyo zithandwa ngabafoti abaninzi ngenxa yokuvula okuphezulu, umgangatho womfanekiso ophezulu, kunye nokuphatheka.Iilensi yokugxila esisigxinainobude obugxininisekileyo, kwaye uyilo lwayo lujolise ngakumbi ekusebenzeni kwamehlo ngaphakathi koluhlu oluthile lwengqwalasela, ekhokelela kumgangatho ongcono womfanekiso.

Ke, ndiyisebenzisa njani ilensi yokugxila esisigxina?Masifunde malunga neengcebiso kunye nezilumkiso zokusebenzisa iilensi ezigxininisiweyo kunye.

Ukusetyenziswa kwelensi yogxininiso ezinzileyo kuneendlela, kwaye ngokusebenzisa obu buchule, umntu unokusebenzisa izibonelelo zelensi kwaye athathe iifoto ezikumgangatho ophezulu:

1.Khetha ubude bojoliso obufanelekileyo ngokusekelwe kwindawo yokudubula

Ubude be-lens egxininisekileyo yogxininiso lugxininisekile, ngoko ke xa uyisebenzisa, kuyimfuneko ukukhetha ubude bogxininiso ngokufanelekileyo ngokusekelwe kwisifundo kunye nomgama odutyulwayo.

Umzekelo, iilensi ze-telephoto zifanelekile ukudubula izifundo ezikude, ngelixa iilensi ezibanzi zifanelekile ukudubula imihlaba emikhulu;Xa udubula imixholo ekude, kunokuba yimfuneko ukuba usondele kubo kancinane, kwaye xa udubula imiboniso emikhulu, kunokuba yimfuneko ukuhlehla umgama othile.

2.Nika ingqalelo ukuchaneka kokugxila kwincwadana

Ngenxa yokungakwazi kweilensi yokugxila esisigxinaukulungelelanisa ubude obugxininisiweyo, umfoti kufuneka ahlengahlengise ugxininiso lwekhamera ukuqinisekisa ukuba umxholo wokufota ugxininise ngokucacileyo.Ukulungelelaniswa kwengqwalasela kunokufezekiswa ngokusebenzisa imisebenzi yokugxila ngokuzenzekelayo okanye ngesandla.

Ezinye iilensi ezigxininisiweyo azikwazi ukugxila kwi-autofocus kwaye zixhasa kuphela ugxininiso lwezandla.Kuyimfuneko ukuba usebenzise kwaye uhlakulele izakhono zokugxila kakuhle ngexesha lokusetyenziswa ukuqinisekisa ukudubula okucacileyo kunye nokubonakalayo kwesifundo.

3.Nikela ingqalelo ekusebenziseni izibonelelo zokuvula indawo enkulu

Iilensi ezigxininisiweyo zihlala zinendawo enkulu yokuvula, ngoko zihlala zithatha iifoto ezicacileyo neziqaqambileyo kwiimeko zokukhanya okuphantsi.

Xa ukudubula, ubunzulu bentsimi kunye nobumnyama obungasemva bunokulawulwa ngokulungelelanisa ubungakanani bokuvula: i-aperture encinci (efana ne-f / 16) inokugcina umfanekiso wonke ucacile, ngelixa i-aperture enkulu (efana ne-f / 2.8) inokudala i-aperture ubunzulu obunzulu besiphumo sebala, ukwahlula umxholo kwimvelaphi.

4.Nika ingqalelo ekuqulunqweni okuneenkcukacha

Ngenxa yobude obungaguqukiyo bokujolisa, ukusebenzisa ilensi yogxininiso ezinzileyo kunokuphucula izakhono zokuqamba, kukuvumela ukuba uqwalasele ngononophelo ulungiselelo lwezinto kunye nokubonakaliswa kwemixholo kumfanekiso ngamnye.
