Uma wenza ushintsho kusuka iphuzu bese udubula amakhamera ku-DSLRs, isici esisodwa se-DSLR esingasidakazela sinquma ukuthi uzosebenzisa nini izindlela ezahlukene zekhamera. Ngaphansi kwe-shutter imodi yokuqala, ikhamera izokuvumela ukuthi usethe isivinini se-shutter esendaweni ethile, bese ikhamera izokhetha ezinye izilungiselelo (njengokuvula noku-ISO) ngokususelwa kusivinini se-shutter oyikhethile.
Isivinini sokuvala yisilinganiso sesikhathi sokuthi ikhamera yekhamera ye-DSLR ivuliwe. Njengoba i-shutter ivulekile, ukukhanya okuvela esihlokweni kushaya inzwa yesithombe sekhamera, kudala isithombe. Ijubane lokuvala okusheshayo lisho ukuthi i-shutter ivulekile isikhathi esifushane, okusho ukukhanya okuncane kufinyelela esithombeni sesithombe. Ijubane le-shutter elincane lisho ukukhanya okukhulu kufinyelela esithombeni sesithombe.
Ukuqaphela uma kuwumqondo omuhle ukusebenzisa imodi yokuvala kuqala kungase ibe yinkimbinkimbi kunokuba uyisebenzise ngempela. Zama lawa macebiso ukuze uthole ukuthi ungayithola kanjani lapho kungcono ukusebenzisa i-shutter kuqala imodi futhi usebenzise ama-shutter esheshayo.
Ukukhanya okwengeziwe kuvumela ukusheshisa okusheshayo okusheshayo
Ngokukhanya kwangaphandle okukhanyayo, ungakwazi ukudubula ngesivinini esisheshayo se-shutter, ngoba ukukhanya okungaphezulu kuyatholakala ukushaya inzwa yesithombe esikhathini esifushane. Ngezimo eziphansi kakhulu, udinga isivinini se-shutter esincane, ngakho ukukhanya okwanele kungabamba inzwa yesithombe ngenkathi i-shutter ivulekile ukudala isithombe.
Izisindo zokuvala ngokushesha zibalulekile ekuthathweni izifundo ezihamba ngokushesha. Uma isivinini se-shutter singasheshi ngokwanele, isihloko esisheshayo singase sibonakale sibukeka esithombeni.
Yilapho i-shutter yokuqala kuqala ingaba nenzuzo. Uma udinga ukudubula isihloko esishukumisayo, ungasebenzisa imodi yokuvala kuqala kuqala ukuze ukhethe isivinini se-shutter esheshayo kunokuba ikhamera ingase ikhethe ngokwayo kwimodi ngokuzenzekelayo. Uzoba nethuba elingcono kakhulu lokuthola isithombe esibukhali.
Ukubeka i-Shutter Mode Priority
Imodi yokuvala kuqala kuqala imakwe nge "S" kumodi yokudonsa ikhamera yakho ye-DSLR. Kodwa ezinye amakhamera, njengezithombe ze-Canon, sebenzisa i-Tv ukuze ubonise imodi yokuvala kuqala. Vula imodi ngokushelela ku- "S," futhi ikhamera izoqhubeka isebenza ngemodi ngokuzenzakalelayo, kodwa izosekela zonke izilungiselelo ezivaliwe ngesivinini se-shutter ozikhetha ngesandla. Uma ikhamera yakho ingenayo ukudayela kwemodi yomzimba, ngezinye izikhathi ungakhetha imodi yokuvala kuqala kwimenyu yamaskrini.
Ngenkathi cishe yonke ikhamera ye-DSLR inemodi yokuvala kuqala, itholakala ngokwengeziwe kuma-camera lens fixed. Ngakho-ke qiniseka ukuthi ubuka kumamenyu wakho wekhamera kusikrini salolu khetho.
Isivinini se-shutter esisheshayo singase sibe ngu-1 / 500th wesibili, esizovela njenge-1/500 noma 500 kusikrini sekhamera yakho ye-DSLR. Isivinini esincane esivamile se-shutter singase sibe yi-1/60 yesibili.
Ukusetha isivinini se-shutter esimweni sokuqala se-shutter, ngokuvamile uzosebenzisa izinkinobho zokuqondisa inkinobho yenkampani yezinkambo ezine, noma ungase ukwazi ukusebenzisa ukudayela komyalo. Kumodi yokuqala ye-shutter, ukulungiselelwa kwejubane lokuvala isivinini ngokuvamile kuzofakwa kuhlu oluhlaza ku-screen yekhamera ye-LCD, kanti ezinye izilungiselelo zamanje zizoba mhlophe. Njengoba ushintsha isivinini se-shutter, singashintsha ngokubomvu uma ikhamera ingakwazi ukudala ukutholakala okusebenzayo esivinini se-shutter oyikhethile, okusho ukuthi kungadingeka ulungise ukulungiselelwa kwe- EV noma ukwandise ukulungiselelwa kwe- ISO ngaphambi kokusebenzisa i-shutter ekhethiwe isivinini.
Ukuqonda Izinketho Zokusekela Ukusheshisa Isivinini
Njengoba ulungisa izilungiselelo zejubane le- shutter , cishe uzothola izilungiselelo ezisheshayo eziqala ngo-1/2000 noma 1/4000 futhi ezingase ziphele ekuvinjeni kancane kancane kwamasekhondi angu-1 noma amabili. Izilungiselelo zizohlala ziba cishe ingxenye noma ziphindwe kabili ngesilungiselelo sangaphambilini, ukusuka ku-1/30 kuya ku-1/60 kuya ku-1/125, nokunye, nakuba ezinye amakhamera zinikeza izilungiselelo ezicacile nakakhulu phakathi kwezilungiselelo ezihamba phambili ze-shutter speed.
Kuzoba nezikhathi lapho ukudubula nge-shutter kuqala lapho ungase ufune ukusebenzisa isivinini se-shutter esincane. Uma uzodubula ngesivinini esincane se-shutter, noma yikuphi okuyi-1/60 noma okuhamba kancane, cishe kuzodingeka i-tripod, i-shutter esilawuliwe, noma i-shutter i-shutter ukuze udubule izithombe. Ekuvinjeni kwe-shutter esheshayo, ngisho nesenzo sokucindezela inkinobho ye-shutter ingahlanganisa ikhamera ngokwanele ukudala isithombe esicacile. Kubuye kunzima kakhulu ukubamba ikhamera ngokuzenzekelayo ngesandla uma kudutshulwa ngesivinini esincane se-shutter, okusho ukunyakaza kwekhamera kungabangela isithombe esicacile kancane, ngaphandle uma usebenzisa i-tripod .
