Enye yezindlela ezilula zokuthuthukisa izithombe zakho ukuqonda ukujula kwensimu-ngamagama alula, ibanga esithombeni sakho phakathi kwento eseduzane ekugxilweni nasekude kakhulu. Imodi yokubaluleka kuqala yilapho nje kuyithuluzi oyidingayo, futhi indlela engcono kakhulu yokufunda ukuthi ungayisebenzisa kanjani ukuzama ukuyisebenzisa.
Kodwa Okokuqala: Kuyini Ukuvula?
Isimo sokuvula silawula ukuthi ingakanani i-lens yakho yekhamera evula ukuthumba isithombe odubulayo. Isebenza okufana nomfundi welihlo: Uma umfundi ehamba phambili, ulwazi olwengeziwe lokukhanya nolwazi lungeniswa ebuchosheni bokucubungula.
Abadwebi bezithombe balinganisa ubukhulu bokuvula ku-f-stops-isibonelo, f / 2, f4, njalonjalo. Ngokuphambene nalokho ongakulindela, ukukhula kwenombolo ku-f-stop kungukuthi, ukubonakala okuncane. Ngakho, i-f / 2 ibonisa ukuvulwa kwamalensi amakhulu kune f / 4. (Cabanga ngenani njengenani lokuvalwa: Inombolo ephakeme isho ukuvalwa okukhulu.)
Ukusebenzisa Imodi Yokuqala Yokuvula Ukulawula Ukujula Kwesizinda
Usayizi wokuvula usebenza ngesivinini se-shutter ukucacisa ukujula kwensimu, engenza noma iphule izithombe zakho. Cabanga ngendawo yokudubula lapho kuphela amasentimitha ambalwa okuqala wesithombe ebukhali noma isithombe sesitulo lapho isizinda saso sibheke ngokulinganayo.
Ukuze ukhethe i-mode yokuvula kuqala, bheka i- A noma i- AV kwimodi yokudayela phezulu kwe- DSLR yakho noma ikhamera yepophu neyokuphambili. Kulo modi, ukhetha ukuvula, futhi ikhamera bese isetha isivinini se-shutter esifanele.
Amathiphu wokudubula ku-Aperture Mode Priority
Uma ukudubula indawo-okudinga ukujula kwenhlabathi okubanzi noma enkulu ukugcina konke kugxilwe-khetha ukuvulwa kwezungeze f16 / 22. Uma udubula into encane njengengcezu yezinto zokucweba, noma kunjalo, ukujula kwensimu encane kuzokusiza ukufiphaza ingemuva bese ususa imininingwane ephazamisayo. Ukujula kwensimu encane kungasiza ukudonsa isibalo esisodwa noma ukukhishwa esixukwini. Ukuphakama phakathi kwe-f1.2 no-f4 / 5.6, kuye ngokuthi ngabe into encane kangakanani, kungaba yisinqumo esihle.
Kulula kakhulu ukukhohlwa ngokuphelele ngejubane le- shutter uma ucacisa ekuvuleni kwakho. Ngokuvamile, ikhamera ngeke ibe nenkinga ukuthola isivinini esifanelekayo, kodwa izinkinga zingavela uma ufuna ukusebenzisa insimu ejulile yensimu ngaphandle kokukhanya okuningi. Lokhu kungenxa yokuthi insimu ejulile yensimu isebenzisa ukuvula okuncane (njenge-f16 / 22), okuvumela ukukhanya okuncane kakhulu ku-lens. Ukuze uhlawulele lokhu, ikhamera kuzodingeka ukhethe isivinini se-shutter esincane ukuvumela ukukhanya okwengeziwe ekhamera.
Ekukhanyeni okuphansi, lokhu kungasho ukuthi ikhamera izokhetha isivinini se-shutter esincane kakhulu ukuba ubambe ikhamera ngesandla ngaphandle kokubangela ukufiphaza. Kulezi zimo, ikhambi elivame kakhulu ukusebenzisa i- tripod . Uma ungenayo i-tripod nawe, ungakwazi ukwandisa i- ISO yakho ukukhokhela ukungabi khona kokukhanya, okuzobe kususwe isivinini sakho se-shutter. Vele uqaphele ukuthi uma ushaya kakhulu i-ISO yakho, umsindo omkhulu uzothola isithombe sakho.
