Fumana i-Camera Viewfinder ukuhlangabezana nezidingo zakho
Isalathisi sekhamera yinto evumela ukuba ubone umfanekiso oza kuthatha. Kukho iintlobo ezahlukeneyo zezibukeli ezisetyenzisiweyo kwiinkhamera ezahlukeneyo zedijithali ezikhoyo namhlanje. Xa kuthengwa ikhamera entsha , kubalulekile ukwazi ukuba uluphi uhlobo lwesibhengezo olufunayo.
Yiyiphi i-Viewfinder?
Isalathisi siphezulu phezulu kweemakhamera zedijithali, kwaye ukhangele kuyo ukuba udale indawo.
Gcina ukhumbule ukuba akuzona zonke iikhamera zedijithali ezine-viewfinder. Ezinye iingongoma kunye nokudubula, ii-compact cameras azibandakanyi isibhengezo, oku kuthetha ukuba kufuneka usebenzise isikrini seLCD ukuze ulungise umfanekiso.
Ngeenkhamera ezibandakanya i-viewfinder, phantse unakho ukhetho lokusebenzisa i-viewfinder okanye i-LCD ukubeka iifoto zakho. Kwezinye iikhamera ze-DSLR le nto ayikhethi.
Ukusebenzisa isibhengezo kunokuba isikrini seLCD sinamathuba ambalwa:
- I-viewfinder idonsa amandla angaphantsi kwebhetri.
- I-viewfinder ikuvumela ukuba uzinze ngakumbi kuba ubambe ikhamera kufuphi nomzimba wakho.
- I-viewfinder yenza uzive njengomfoto wezonene!
Emva kokuba usetyenziswe ukusebenzisa i-viewfinder yakho yekhamera ungasoloko utshintsha i-camera controls ngaphandle kokujonga kude.
Kukho iintlobo ezintathu ezahlukeneyo zokubukela ikhamera.
I-Optical Viewfinder (kwi-Digital Compact Camera)
Le yinkqubo elula apho i-viewfinderfinder ye-optical izama khona ngexesha elifanayo njenge-lens enkulu. Umzila walo optical uhambelana nomlingo nakuba awukubonisi kakuhle oko kusemzimbeni wesakhiwo.
Abajonga kwi-compact, iphuzu kunye nokudubula iikhamera bahlala bebancinci, kwaye bahlala bebonisa kuphela malunga ne-90% yento esiza kuyithatha. Oku kwaziwa ngokuba yi "mpazamo ye-parallax," kwaye ibonakala kakhulu xa izifundo zikufutshane nekhamera.
Kwiimeko ezininzi, kuchanekile ngakumbi ukusebenzisa isikrini seLCD.
I-Optical Viewfinder (kwi-kamera ye-DSLR)
I-DSLR isebenzisa isibuko kunye ne-prism kwaye oko kuthetha ukuba akukho mpazamo ye-parallax. I-viewfinder ye-optical (OVF) ibonisa oko kuza kuvela kwi-sensor. Oku kubizwa ngokuthi "ngokusebenzisa iteknoloji", okanye i-TTL.
I-viewfinder ibonisa ibha yomgangatho ngaphantsi, ebonisa ulwazi lokumisa kunye nekhamera. Kwiinkampu ezininzi ze-DSLR uza kubona kwaye ukwazi ukukhetha kwiindawo ezahlukeneyo ze-autofocus, ezibonakala njengeebhokisi zeekwere ezincinane kunye nekhethiweyo ezigqityiweyo.
I-Electronic Viewfinder
I-viewfinder ye-elekthronikhi, ngokufuthi ifutshane kwi-EVF, iphinda iteknoloji yeTTL.
Isebenza ngendlela efanayo kwesikrini seLCD kwikhamera yekhampani, kwaye ibonisa umfanekiso ovezwe kwi-sensor lens. Oku kuboniswa ngexesha langempela nangona kukho ukulibaziseka.
Ngokwenene, i-EVF iyi-LCD encinci, kodwa ichaza umphumo wababukeli abafumaneka kwi-DSLRs. I-EVF ayifuni neengxaki zeparallax.
Abanye ababukeli be-EVF baza kukunika ingqiqo kwimisebenzi eyahlukeneyo okanye izilungiso eziza kuthathwa ikhamera. Unokubona iinkalo ezigqityiweyo ezicacisa inkcazo ikhamera iya kugxininisa okanye ingafanisa ukugquma kwesibheno esiya kubanjwa. I-EVF inokukhuthaza ukukhanya ngokuzenzekelayo kwimifanekiso emnyama kwaye ubonise ukuba kwesikrini.
