Isici Sokubuka Bukhoma Kwekhamera Yedijithali
Enkathini yanamuhla yezobuchwepheshe besimanje, amakhamera edijithali athuthuke ngokushesha, kokubili ngokwehadiwe kanye nesofthiwe. Esinye isici esiye saba yindawo yokushintsha ekusetshenzisweni kwamakhamera edijithali yi-Live View. Lesi sici sivumela abathwebuli bezithombe ukuthi babone umbono obukhoma wenzwa yesithombe esikrinini se-LCD sekhamera. Kulesi sihloko, sizoxoxa ngokujulile nge-Live View, ukuthi isebenza kanjani, izinzuzo zayo kanye nokungalungi kwayo, kanye namathiphu okuyisebenzisa ukuthuthukisa ikhwalithi yezithombe zakho.
Ukuqonda Isici Sokubuka Okubukhoma
I-Live View iyisici kumakhamera edijithali esivumela abasebenzisi ukuthi babuke kuqala isithombe ngesikhathi sangempela esikrinini se-LCD noma ku-electronic viewfinder (EVF). Lesi sici sishintsha indlela abathwebuli bezithombe abaxhumana ngayo nekhamera, kusukela ekusebenziseni i-optical viewfinder kuya kusibonisi sedijithali. Amakhamera e-Digital SLR ayengenye yezinhlobo zokuqala zamakhamera ezamukela kabanzi lesi sici, yize namuhla i-Live View ivame ukutholakala kumakhamera angenazibuko ngisho namakhamera amancane.
Indlela Isici Sokubuka Okubukhoma Esisebenza Ngayo
Isici se-Live View sisebenza ngokuthwebula ukukhanya okungena ngelensi yekhamera bese sikuqondisa ngqo ku-sensor yesithombe. Le sensor ibe isihumusha ukukhanya ekwamukelayo kube isignali yedijithali, ecutshungulwa yi-processor yekhamera bese ekugcineni iboniswa esikrinini se-LCD noma i-EVF.
Kumakhamera e-DSLR avamile, isibuko esiqondisa ukukhanya kusibonisi sokubona esibonakalayo sivame ukuvimba inzwa yesithombe. Ukuze kusebenze i-Live View, lesi sibuko kumele siphakanyiswe endaweni yaso yokukhiya ukuze ukukhanya kufinyelele ngqo kunzwa. Lona omunye wemehluko oyisisekelo phakathi kokusebenzisa isibonisi sokubona esibonakalayo kanye ne-Live View. Amakhamera angenasibuko, ngakolunye uhlangothi, awanaso isibuko, ngakho-ke i-Live View ingahlala isebenza ngaphandle kokucutshungulwa okwengeziwe.
Izinzuzo zesici se-Live View
1. Ukwakheka Kwesithombe Okunembe Kakhulu
Ngesici se-Live View, abathwebuli bezithombe bangabona ukwakheka okugcwele kwesithombe esikrinini se-LCD. Lokhu kuyasiza ekuhloleni imininingwane emincane, ukuqinisekisa umugqa oqondile we-horizon, kanye nokulungisa ukwakheka. Nge-optical viewfinder, izithunzi ezingaphandle noma ukuhlanekezela kungaba yinkinga, kodwa nge-Live View, ukwakheka kwesithombe kungaqashwa eduze kakhulu.
2. Ukugxila Okunembile
I-Live View ivame ukufaka isici sokugxila phezulu, esiphawula indawo yesithombe egxile ngombala othize. Lokhu kuyasiza kakhulu ezimweni zokugxila ngesandla noma uma usebenzisa ilensi enensimu encane kakhulu.
3. Kulula Ukulawula Ukuchayeka
I-Live View ivumela abathwebuli bezithombe ukuthi babone izinguquko zokuchayeka ngqo esikrinini. Uma ushintsha izilungiselelo ezifana ne-ISO, i-aperture, kanye nesivinini sokushaja, imiphumela ingabonakala ngesikhathi sangempela. Lokhu kusiza kakhulu ekuqinisekiseni ukuchayeka okufanele ngaphambi kokuthatha isithombe.
4. Uhlaka Oluguquguqukayo
Isikrini se-LCD kumakhamera edijithali ane-Live View sivame ukutsheka noma ukujikeleza. Lokhu kunikeza ukuguquguquka okubaluleke kakhulu lapho uthwebula kusuka kuma-engeli anzima, njengaphansi noma phezulu, ngaphandle kokushintsha kakhulu isikhundla somzimba wakho.
Ubuthakathaka besici se-Live View
1. Ukusetshenziswa Kwebhethri Okusheshayo
Enye yezingqinamba ezinkulu zokusebenzisa i-Live View ukusetshenziswa kwayo kwamandla okusheshayo. Isikrini se-LCD esihlala sivuliwe kanye neprosesa esebenza njalo ukucubungula isithombe sokubuka bukhoma kudinga amandla engeziwe. Lokhu kunganciphisa kakhulu impilo yebhethri uma kuqhathaniswa nokusebenzisa i-optical viewfinder.
2. Ukubambezeleka kanye nokubambezeleka
Nakuba amakhamera amaningi anamuhla eyithuthukisile le nkinga, kusekhona ukubambezeleka okuncane phakathi kwalokho okwenzekayo phambi kwelensi nalokho okuboniswa esikrinini. Lokhu kubambezeleka kungaba yinto ecasulayo ikakhulukazi ekuthwebuleni izithombe ezisheshayo lapho ukunemba kwesikhathi kubalulekile khona.
3. Ukushisa ngokweqile
Ukusetshenziswa okuqhubekayo kwenzwa yesithombe kumodi ye-Live View kungabangela ukushisa ngokweqile. Inzwa yesithombe ikhiqiza ukushisa ngesikhathi sokusebenza okuqhubekayo, okungathinta ukusebenza kwekhamera iyonke, okuhlanganisa ikhwalithi yesithombe kanye nesikhathi sokuphila kwedivayisi.
Amathiphu Okusebenzisa Isici Sokubuka Okubukhoma
1. Sebenzisa i-Tripod ukuze Uzinze
Uma usebenzisa i-Live View, ikakhulukazi ezimweni lapho isivinini se-shutter sihamba kancane noma ukujula kwensimu kuncane kakhulu, ukusetshenziswa kwe-tripod kunconywa kakhulu. Lokhu kusiza ekuqedeni ukunyakazisa kwekhamera futhi kuqinisekisa izithombe ezicacile nezicacile.
2. Sebenzisa ithuba le-Focus Peaking bese usondeza i-Zoom In
Ukuze uqinisekise ukugxila okunembe kakhulu, sebenzisa izici zokugxila okuphezulu kanye nezici zokukhulisa i-focus ku-Live View. Lokhu kuwusizo ikakhulukazi ezithombeni ze-macro noma ze-portrait, lapho ukugxila okuningiliziwe kubalulekile khona.
3. I-Histogram Yokuqapha
Noma nini lapho kungenzeka, qapha i-histogram esikrinini se-LCD uma usebenzisa i-Live View. I-histogram inikeza umbono onembile wokusatshalaliswa kokuchayeka kunokuthembela kuphela esibukweni esisesikrinini. Lokhu kusiza ukugwema ukuchayeka okungaphelele noma ukuchayeka ngokweqile.
4. Sebenzisa Imodi Yokudubula Ethule
Amanye amakhamera anikeza imodi yokudubula buthule uma usebenzisa i-Live View, lapho i-mechanical shutter ingasetshenziswa khona. Le modi yehlisa umsindo nokudlidliza ngesikhathi sokudubula, okuwusizo ezimweni lapho ukuthula kubalulekile noma ukunciphisa ukudlidliza uma usebenzisa isivinini se-shutter esihamba kancane.
5. Naka ukukhanya okuzungezile
Uma usebenzisa i-Live View ngaphandle, ikakhulukazi elangeni elikhanyayo, isikrini se-LCD singase sibe nzima ukusibona. Sebenzisa i-monitor esezingeni eliphezulu noma i-sun hood ukuze unciphise ukukhanya nokuqinisekisa ukuthi ubuka kahle.
Isiphetho
Isici se-Live View kumakhamera edijithali sinikeza izinzuzo ezibalulekile ekuthwebuleni izithombe zesimanje. Kusukela ekwakhiweni kwesithombe okunembile kakhulu kanye nokugxila okunembile kuya ekulawuleni ukuchayeka okungcono, i-Live View ishintshe indlela abathwebuli bezithombe abasebenza ngayo namakhamera abo. Kodwa-ke, kubalulekile futhi ukuqaphela izinkinga ezingaba khona, njengokukhipha ibhethri ngokushesha kanye nokushisa ngokweqile okungenzeka.
Ngokuqonda ukuthi ungasisebenzisa kanjani lesi sici ngempumelelo, abathwebuli bezithombe bangenza ngcono izithombe zabo futhi bathole imiphumela engcono. Njengabo bonke ubuchwepheshe, isihluthulelo ukuqonda ukulinganiselwa kwayo nokuthola izindlela zokwandisa amandla ayo. I-Live View iyithuluzi elibalulekile ezandleni ezifanele futhi ingangeza inani elikhulu ezinhlobonhlobo zezitayela zezithombe.
