Usebenzisa njani i-lens egxile kuyo? Iingcebiso kunye namanyathelo okusebenzisa iilensi ekugxilwe kuzo

Iilensi ekugxilwe kuzo zithandwa ngabantu abaninzi ngenxa yokuphambana okuphezulu, umgangatho ophezulu, kunye nokuchaphazeleka. II-lens ekugxilwe kuyoUnobude obubi bokugxila, kwaye uyilo lwayo lugxile kwintsebenzo ye-Optical ngaphakathi kuluhlu olujolise ngqo, okukhokelela kumgangatho womfanekiso ongcono.

Ke, ndisebenzisa njani ilensi ekugxilwe kuyo? Masifunde malunga neengcebiso kunye nezilumkiso zokusebenzisa iilensi ekugxilwe kuzo kunye.

Iingcebiso kwayepUkuphinda uphinda kwakhonafor uculafixiledfi-ocuslinokwenzeka

Ukusetyenziswa kwelensi ekugxilwe kuzo kuneendlela zobuchule, kwaye ngokusebenzisa ezi ndlela, umntu unokunyusa izibonelelo zelensi kwaye uthathe iifoto ezisemgangathweni eziphezulu:

1.Khetha ubude obufanelekileyo ngokusekwe kwindawo yokudubula

Ubude obugxile kwilensi yokugxila ekugxilwe kuyo buhleliwe, ke xa kuyisebenzisa, kuyimfuneko ukukhetha ubude obujolise ngokusekelwe kwisifundo kunye nomgama wokudutyulwa.

Umzekelo, iilensi zeTelephoto zilungele ukudubula izifundo ezikude, ngelixaI-angle-anglezilungele ukudubula imimandla enkulu; Xa udubule imixholo ehambela phambili, kunokuba yimfuneko ukuba ube kufutshane, kwaye xa udubula imigangatho emikhulu, kunokuba yimfuneko ukuba ibuye umva umgama.

2.Nika ingqalelo ukuchaneka kwencwadana yokujonga

Ngenxa yokungakwazi konkeI-lens ekugxilwe kuyoUkulungelelanisa ubude bembali, umfoti kufuneka alungelelanise ugxininiso lwekhamera ukuqinisekisa ukuba umxholo we-dud ugxile ngokucacileyo. Uhlengahlengiso loqwalaselo lunokufezekiswa kusetyenziswa imisebenzi ezenzekelayo okanye yokugxila yencwadana.

Ezinye iilensi zogxininiso ezingapheliyo azikwazi ukulungisa i-autofocus kunye nencwadana yokuxhasa ukugxila. Kuyimfuneko ukuba uziqhelise kwaye uhlakulele izakhono ezilungileyo zokugxila ngexesha lokusetyenziswa ukuqinisekisa ukudubula ngokucacileyo nangokucacileyo kwesihloko.

3.Nika ingqalelo ekusebenziseni izibonelelo ze-aperture enkulu

Iilensi ekugxilwe kuzo zisiqhelo zihlala zinezinto ezinkulu, ngoko ke zihlala zibamba iifoto ezicacileyo nezikhanyayo kwiimeko eziphantsi.

Xa ukudubula, ubunzulu bentsimi kunye nemvelaphi blir bunokulawulwa ngokuhlengahlengiswa ubungakanani be-aperture: i-aperture encinci (efana ne-f / 16) inokuwugcina umfanekiso wonke, ngelixa i-f / 2.8) inokwenza i Ubunzulu bemithombo yentsimi, ukwahlula umxholo ukusuka kwimvelaphi.

4.Nika ingqalelo ekuqulunqweni okuneenkcukacha

Ngenxa yobude obubi bokugxila, usebenzisa ilensi yokugxila ekugxilwe kuyo inokuphucula izakhono zezakhono, ukuvumela ukuba uqwalasele ngononophelo ulungiselelo lwezinto kunye nentetho yemifanekiso nganye.
