Ukuvezwa ngokuzenzekelayo (AE), ngezinye izikhathi ukufinyelelwa ekuchazeni ngokuzenzakalela, kuyisistimu yekhamera yedijithali ezenzakalelayo ebeka isivinini sokuvula kanye / noma isivinini, ngokusekelwe ezimweni zangaphandle zokukhanyisa zesithombe. Ikhemikhali yenza ukukhanya kuhlaka bese ivala ngokuzenzekelayo izilungiselelo zekhamera ukuqinisekisa ukutholakala okufanele.
Ukuvezwa kahle kufanele kubaluleke kakhulu, njengesithombe lapho ikhamera engalingani khona ukukhanya ngokufanele kuyophela ekugcineni kakhulu (ukukhanya okuningi esithombeni) noma ukungaqondakali (ukukhanya okuncane kakhulu). Ngesithombe esiphezulu, ungaqeda ukulahlekelwa imininingwane esiteshini, njengoba uzoba nezindawo ezimhlophe ezimhlophe esithombeni. Ngesithombe esingafakiwe, isimo sizoba mnyama kakhulu ukuze sithole imininingwane, sishiye umphumela ongathandeki.
Ukucaciswa okuzenzakalelayo kuchaziwe
With amakhamera amaningi digital, akudingeki ngempela ukwenza lutho olukhethekile noma ushintshe noma yiziphi izilungiselelo ezithile ukuze ikhamera basebenzise ukuchayeka okuzenzakalelayo. Uma ukudubula ngezindlela ezizenzakalelayo ngokuzenzakalelayo, ikhamera ilungisa zonke izilungiselelo ngokwayo, okusho ukuthi i-photographer ayinakho ukulawula.
Uma ufuna kancane ukulawulwa kwamandla, amakhamera amaningi anikezela okukhethwa kukho okulinganiselwe okuncane, kodwa ikhamera ingaqhubeka isebenzisa ukuzitholela okuzenzakalelayo. Abathwebuli bezithombe ngokuvamile bangakhetha eyodwa yezindlela ezintathu zokudubula ezihlukene ngokulawulwa okulinganiselwe ngesikhathi ugcina i-AE:
- Ukuqala kokuvula kuqala kuvumela umthwebuli wezithombe ukusetha inani lokuvula, bese ikhamera yedijithali inqume ngokuzenzekelayo isivinini se-shutter ukudala ukuvezwa okuzenzakalelayo okuzenzakalelayo.
- Ukuvala kuqala kuvumela umthwebuli wezithombe ukusetha isivinini se-shutter, bese ikhamera yedijithali inquma ngokuzenzakalelayo ukuvula ukudala ukuvezwa okuzenzakalelayo.
- Imodi yohlelo ivumela umthwebuli wezithombe ukuthi enze izinguquko ku-speed shutter, ukuvula, noma kokubili, kanye nekhamera yedijithali bese ubeka ngokuzenzakalelayo i-ISO ukudala ukuvezwa okuzenzakalelayo okuzenzakalelayo.
Yiqiniso, nawe ungakwazi ukulawula ngokukhethekile ukuvezwa kwesimo ngokudubula ngokugcwele imodi yokulawula i-manual. Kulo modi, ikhamera ayenzi izinguquko ezilungiselelweni. Esikhundleni salokho, ithembela kumthwebuli wezithombe ukwenza zonke izinguquko ngesandla, futhi lezi zilungiselelo ziphelela ekunqumeni amazinga wokungena endaweni yesehlakalo, njengoba izilungiselelo ngasinye zisebenza ngokulandelana.
Ukwenza Ukusetshenziswa Okuzenzakalelayo
Amakhamera amaningi azobeka ukuvezwa okuzenzekelayo ngokusekelwe ekukhanyeni phakathi kwendawo yesehlakalo.
Noma kunjalo, ungasebenzisa ukwakheka okungekho emkhakheni futhi ukhiye ku-AE ngokugxilisa into oyifunayo ngokucacile. Bese ubambe inkinobho ye-shutter isigamu noma cindezela inkinobho ye-AE-L (AE-Lock) . Yenza kabusha isimo bese ucindezela ngokugcwele inkinobho ye-shutter.
Ukulungisa i-AE ngesandla
Uma ungafuni ukuthembela ekhamera ukusetha ukuchayeka ngokuzenzekelayo, noma uma udutshulwa isiteji ngezimo ezikhanyayo ezikhanyayo lapho ikhamera engakwazi ukubonakala sengathi ingena kuzilungiselelo ezifanele ukudala ukuvezwa okufanele , unokukhetha ukulungisa i-AE yekhamera.
Amakhamera amanengi anika i-EV (ukuhlunga ukulinganisa) , lapho ungalungisa khona ukukhanya. Kwamanye amakhamera ahamba phambili, i-EV setting iyinkinobho ehlukile noma idayida. Ngamakhamera wezinga eliqala, ungase usebenze kumamenyu wekhamera esesikrinini ukuze ulungise ukulungiselelwa kwe-EV.
Setha i-EV kwinamba engalungile ukuze unciphise inani lokukhanya elifinyelela enzwa yesithombe, eliwusizo uma ikhamera idala izithombe ezithuthukisiwe ezisebenzisa i-AE. Futhi ukubeka i-EV enombolweni enhle kwandisa isibalo sokukhanya esifinyelela esithombeni sesithombe, esetshenziswe lapho i-AE ingakhulumi izithombe.
Ukuba nokuchayeka okuzenzakalelayo kuyisihluthulelo sokwakha isithombe esingcono kunakho konke, ngakho-ke qaphela lokhu kulungiselelwa. Esikhathini esiningi, i-AE yekhamera yenza umsebenzi omuhle wokurekhoda isithombe ngokukhanyisa okufanele. Kulezo zikhathi lapho i-AE ihlukumezeka, noma kunjalo, ungesabi ukwenza izinguquko ku-EV ukubeka lapho kudingeka!
