Thola i-Camera Viewfinder Yokuhlangabezana Nezidingo Zakho
I-viewfinder yekhamera yilokho okukuvumela ukuba ubone isithombe ozoyithatha. Kunezinhlobo ezahlukene zezibukeli ezisetshenziswe kumakhamera ahlukahlukene adijithali atholakala namhlanje. Uma uthenga ikhamera entsha , kubalulekile ukwazi ukuthi uluhlobo luni lwesilondolozi oyifunayo.
Iyini isifiso sokubuka?
I-viewfinder itholakala phezulu ngemuva kwekhamera yedijithali, futhi ubukeka ngayo ukuze ubhale isiteji.
Khumbula ukuthi akuzona zonke amakhamera zedijithali enesidingo sokubuka. Iphuzu elilodwa futhi lidubule, amakhamera ahlanganiswe angahlanganisi isibhengezi, okusho ukuthi kufanele usebenzise isikrini se-LCD ukuze uhlele isithombe.
Ngamakhamera afaka isikhangiso, cishe usukhetha njalo ukusebenzisa i-viewfinder noma iLCD ukuze uhlele izithombe zakho. Kwezinye amakhamera we-DSLR lokhu akuyona inketho.
Ukusebenzisa i-viewfinder kune-screen ye-LCD kunezinzuzo ezimbalwa:
- I-viewfinder idonsa amandla angaphansi kwebhethri.
- I-viewfinder ivumela ukuzinza okungcono ngoba ubambe ikhamera eduze nomzimba wakho.
- I-viewfinder yenza uzizwe njengomthwebuli wezithombe wangempela!
Uma usujwayele ukusebenzisa i-viewfinder yakho yekhamera ungashintsha ngokuzenzakalelayo izilawuli zekhamera ngaphandle kokubuka kude.
Kunezinhlobo ezintathu ezahlukene zezibukeli zekhamera.
Isibuko sokubuka (ku-Camera Compact Digital)
Lolu uhlelo olulula kakhulu lapho i-viewfinder yokubuka ivula khona ngesikhathi esisodwa njenge-lens enkulu. Indlela yayo yokukhanya ihamba ngokufana ne-lens nakuba ingakubonisi ncamashi ukuthi kukhonini lesithombe.
Ababukeli be-compact, iphuzu kanye nokudubula amakhamera bavame ukuba abancane kakhulu, futhi bavame ukukhombisa cishe amaphesenti angama-90 walokho okuzobanjwa khona inzwa. Lokhu kwaziwa ngokuthi "iphutha le-parallax," futhi liyabonakala lapho izihloko ziseduze nekhamera.
Ezimweni eziningi, kunembile kakhulu ukusebenzisa isikrini se-LCD.
Isibuko sokubuka (ku-ikhamera ye-DSLR)
I-DSLR isebenzisa isibuko ne-prism futhi lokho kusho ukuthi ayikho iphutha le-parallax. I-viewfinder yokubuka (i-OVF) ibonisa lokho okuzokwenziwa kwinzwa. Lokhu kubizwa ngokuthi "ngokusebenzisa ubuchwepheshe be-lens", noma i-TTL.
I-viewfinder iphinda ibonise ibha yesimo phansi ngezansi, ekhombisa ulwazi lokuchayeka kanye nekhamera. Kuzo zonke amakhamera we-DSLR uzobona futhi ukwazi ukukhetha kusuka kumaphuzu ahlukahlukene we-autofocus, avela njengamabhokisi wesigcawu amancane nomuntu okhethiwe ogqanyisiwe.
Isibukeli se-Electronic View
I-viewfinder ye-elekthronikhi, evame ukufushaniswa ku-EVF, iphinde ibe nobuchwepheshe be-TTL.
Isebenza ngendlela efanako kwisikrini se-LCD kwikhamera ehambelanayo, futhi ibonisa ukuthi isithombe sihlolwe esithombeni ngilensi. Lokhu kuboniswa ngesikhathi sangempela nakuba kungase kube khona ukulibaziseka.
Ngokuyisisekelo, i-EVF iyi-LCD encane, kodwa ichaza umphumela wabathengi abatholakala kwi-DSLRs. I-EVF ayifuni neze amaphutha we-parallax.
Abanye ababukeli be-EVF bazokwazisa futhi ngemisebenzi ehlukahlukene noma izilungiso ezithathwa ikhamera. Ungabona izindawo eziqokonywe ezicacisa iphuzu ikhamera ezogxila kulo noma ingase ifanise ukufiphaza kokuhamba okuzobanjwa. I-EVF ingase iphinde ikhulise ukukhanya ngokuzenzekelayo emaceleni amnyama bese ubonisa ukuthi esikrinini.
