i-engile ebanzi ezemidlalo i-lens yekhamera ye-DV
Ilensi enekona ebanzi:
Ukuthatha ikhamera ye-reflex yekhamera ye-35mm enye njengomzekelo, i-lens ebanzi-engile idla ngokubhekisa kwilensi enobude obugxile kwi-17 ukuya kwi-35mm.
Isici esisisiseko se-wide-angle lens kukuba i-lens ine-angle enkulu yokujonga kunye nommandla obanzi wombono.Uluhlu lwembonakalo yelizwe ngokwembono ethile lulukhulu ngakumbi kunolo olubonwa ngamehlo abantu kwimbono efanayo;Ubunzulu bendawo bude, obunokubonisa uluhlu olucacileyo olucacileyo;Iyakwazi ukugxininisa impembelelo yembono yomfanekiso, ibe yinto efanelekileyo ekugqithiseni ithemba kunye nokuvakalisa ingqiqo yomgama kunye nokuba kufuphi kwendawo, ekhuthaza ukunyusa ukuthandwa komfanekiso.
Iimpawu eziphambili zelensi ebanzi:
1. I-angle yokujonga ebanzi, enokugubungela uluhlu olubanzi lwembonakalo.Into ebizwa ngokuba yi-angle enkulu yokujonga i-angle ithetha ukuba indawo yokujonga efanayo (umgama osuka kwisifundo uhlala ungatshintshi) udutyulwe ngobude obuthathu obuhlukeneyo be-angle-angle, umgangatho kunye ne-telephoto.Ngenxa yoko, eyangaphambili ithatha izigcawu ezininzi phezulu, ezantsi, ekhohlo nasekunene kuneyamva.Xa umfoti engenandlela yokuphuma, ukuba kunzima ukuthatha umfanekiso opheleleyo wendawo kunye ne-lens eqhelekileyo ye-50mm (njengeefoto ezihlangeneyo zabalinganiswa, njl.), unokusombulula ngokulula ingxaki ngokusebenzisa iimpawu zobubanzi- i-lens ye-engile enoluhlu olubanzi lwee-engile zokujonga.Ukongeza, umzekelo, ukudubula amabala amakhulu okanye izakhiwo ezide ezixekweni zinokubamba kuphela indawo yesiganeko nge-lens eqhelekileyo, engakwaziyo ukubonisa ububanzi okanye ubude bendawo.Ukudubula nge-lens ebanzi-engile kunokubonisa ngokufanelekileyo ukukhawuleza okuvulekileyo kwendawo enkulu okanye ubungangamsha bezakhiwo eziphakamileyo emafini.
2. Ubude obufutshane bojoliso kunye nobunzulu bomboniso omde.Xa bethwebula imiboniso ebanzi, abafoti bathembela ngokubanzi kwiimpawu zobude obufutshane obugxile kwilensi ebanzi kunye nobunzulu obude bendawo ukuzisa yonke imbonakalo ukusuka kufutshane ukuya kude kumda womsebenzi ocacileyo.Ukongezelela, xa ukudubula nge-lens-angle-wide-angle, ukuba i-aperture encinci isetyenziswe ngexesha elifanayo, ubunzulu bebala lendawo buya kuba lude.Ngokomzekelo, xa umfaki-zithombe esebenzisa i-28mm ye-angle-angle lens ukudubula, kugxininiswa kwisifundo malunga ne-3M, kwaye i-aperture ibekwe kwi-F8, ngoko phantse bonke bangena kubunzulu bentsimi ukusuka kwi-1m ukuya kwi-infinity.Kungenxa yeempawu zolu bude bunzulu bebala apho i-lens ebanzi-engile isoloko isetyenziswa ngabafoti njengelensi yokufota ekhawulezayo enokushukumiseka okuqinileyo.Kwezinye iimeko, abafoti banokugqiba ukuthwebula ngokukhawuleza ngaphandle kokugxila kumxholo.
3. Ukwazi ukugxininisa ithemba kwaye ubalaselise uthelekiso phakathi kwekude nakufuphi.Lo ngomnye umsebenzi obalulekileyo welensi ebanzi.Okubizwa ngokuba lugxininiso olungaphambili kunye nokugqamisa umahluko phakathi kokude nokufutshane kuthetha ukuba i-lens ebanzi inokugxininisa umahluko phakathi kwe-lens ekufutshane, ekude kunye nencinci kunezinye iilensi.Ngamanye amazwi, iifoto ezithathwe nge-lens-angle-wide-angle zinezinto ezinkulu ezikufutshane kunye nezinto ezincinci ezikude, ezenza abantu bazive ngathi bavule umgama kwaye bavelise impembelelo yombono oqinileyo kwicala lobunzulu.Ngokukodwa xa ukudubula nge-ultra-wide-angle-engile lens kunye nobude obufutshane bokugxila, isiphumo sokukufutshane nesikhulu esincinci sibaluleke kakhulu.
4. Inokubaxwa kwaye ikhubazeke.Ngokuqhelekileyo, umbandela ubaxo kwaye ukhubazekile, nto leyo iyinto enkulu ekusetyenzisweni kwelensi ebanzi.Enyanisweni, akufuneki ukuba umbandela ubaxiswe ngokufanelekileyo kwaye ukhubazeke.Abafoti abanamava basoloko besebenzisa iilensi ezibanzi ukugqwesa umxholo kwaye bathathe imifanekiso engaqhelekanga yeminye imiboniso engabalulekanga kakhulu abantu abangayihoyiyo.Ngokuqinisekileyo, ukubonakaliswa kokugqithisa kunye nokuguqulwa nge-lens ebanzi-engile kufuneka kusekelwe kwiimfuno zomxholo, kwaye ngaphantsi kwaye kulungile.Kungakhathaliseki ukuba umbandela uyadingeka okanye cha, akwanelanga ukusebenzisa kakubi ukugqithisa kunye nokuguqulwa kwe-lens ebanzi kunye nokulandela ngokungaboniyo umphumo ongaqhelekanga kwifomu.
