Ungayisebenzisa njani iLensi yoQoqosho oluZinzileyo? Iingcebiso kunye namanyathelo okuzikhusela xa usebenzisa iiLensi zoQoqosho oluZinzileyo

Iilensi zokugxila ezizinzileyo zithandwa ngabafoti abaninzi ngenxa yokuba zivuleka kakhulu, zinomgangatho ophezulu womfanekiso, kwaye ziyaphatheka lula.ilensi yokugxila esisigxinainobude obungaguqukiyo befocal, kwaye uyilo lwayo lugxile kakhulu ekusebenzeni kwe-optical ngaphakathi koluhlu oluthile lwefocal, nto leyo ekhokelela kumgangatho womfanekiso ongcono.

Ngoko ke, ndiyisebenzisa njani ilensi yokugxila esisigxina? Masifunde ngeengcebiso kunye namanyathelo okusebenzisa iilensi zokugxila ezisisigxina kunye.

Iingcebiso kunyepizilumkisofor uculafixedfi-ocusliingqondo

Ukusetyenziswa kwelensi egxile kwingqwalasela esisigxina kuneendlela zobugcisa, kwaye ngokusebenzisa ezi ndlela, umntu unokusebenzisa iingenelo zelensi aze athathe iifoto ezisemgangathweni ophezulu:

1.Khetha ubude obufanelekileyo bokugxila ngokusekelwe kwindawo yokudubula

Ubude befocal lens yefocus esisigxina buzinzile, ngoko ke xa uyisebenzisa, kuyimfuneko ukukhetha ubude befocal ngokusekwe kumxholo kunye nomgama othathwayo.

Umzekelo, iilensi ze-telephoto zifanelekile ukudubula izinto ezikude, ngelixaiilensi ezineekona ezibanzizifanelekile ukufota iindawo ezinkulu; Xa ufota imixholo ekude, kusenokufuneka usondele kancinci kuzo, kwaye xa ufota imiboniso emikhulu, kusenokufuneka ubuye umva umgama othile.

2.Nika ingqalelo ekuchanekeni kokugxila ngesandla

Ngenxa yokungakwazi kweilensi yokugxila esisigxinaukuze kulungiswe ubude befota, umfoti kufuneka alungise ifota yekhamera ukuqinisekisa ukuba umxholo wefota ugxile ngokucacileyo. Ukulungiswa kwefota kunokufezekiswa ngokusebenzisa imisebenzi yokugxila ngokuzenzekelayo okanye ngesandla.

Ezinye iilensi zokugxila ezizinzileyo azikwazi ukugxila ngokuzenzekelayo kwaye zixhasa kuphela ukugxila ngesandla. Kubalulekile ukuziqhelanisa nokukhulisa izakhono ezilungileyo zokugxila ngexesha lokusebenzisa ukuqinisekisa ukudubula okucacileyo nokubonakalayo komntu ochaphazelekayo.

3.Nika ingqalelo ekusebenziseni iingenelo zokuvula okukhulu

Iilensi ezigxileyo ezizinzileyo zihlala zinesithuba esikhulu, ngoko ke zihlala zikwazi ukuthwebula iifoto ezicacileyo nezikhanyayo kwiimeko zokukhanya okuphantsi.

Xa kufotwa, ubunzulu bebala kunye nokufiphala kwemvelaphi kunokulawulwa ngokulungelelanisa ubungakanani bebala: ibala elincinci (elifana ne-f/16) linokugcina umfanekiso wonke ucacile, ngelixa ibala elikhulu (elifana ne-f/2.8) linokudala ubunzulu obungaphantsi kwesiphumo sebala, lahlula umxholo kwibala elingasemva.

4.Nika ingqalelo kulwakhiwo oluneenkcukacha

Ngenxa yobude obungaguqukiyo befocal, ukusebenzisa ilensi yokugxila engaguqukiyo kunokuphucula izakhono zokuqamba, okukuvumela ukuba uqwalasele ngononophelo ulungelelwaniso lwezinto kunye nokubonakaliswa kwemixholo kumfanekiso ngamnye.
